This module also exposes a typedef `Path` which is equal to the +appropriate platform-specific path variant. + +Both `PosixPath` and `WindowsPath` implement a trait `GenericPath`, which +contains the set of methods that behave the same for both paths. They each also +implement some methods that could not be expressed in `GenericPath`, yet behave +identically for both path flavors, such as `.component_iter()`. + +The three main design goals of this module are 1) to avoid unnecessary +allocation, 2) to behave the same regardless of which flavor of path is being +used, and 3) to support paths that cannot be represented in UTF-8 (as Linux has +no restriction on paths beyond disallowing NUL). + +## Usage + +Usage of this module is fairly straightforward. Unless writing platform-specific +code, `Path` should be used to refer to the platform-native path. + +Creation of a path is typically done with either `Path::new(some_str)` or +`Path::new(some_vec)`. This path can be modified with `.push()` and +`.pop()` (and other setters). The resulting Path can either be passed to another +API that expects a path, or can be turned into a &[u8] with `.as_vec()` or a +Option<&str> with `.as_str()`. Similarly, attributes of the path can be queried +with methods such as `.filename()`. There are also methods that return a new +path instead of modifying the receiver, such as `.join()` or `.dir_path()`. + +Paths are always kept in normalized form. This means that creating the path +`Path::new("a/b/../c")` will return the path `a/c`. Similarly any attempt +to mutate the path will always leave it in normalized form. + +When rendering a path to some form of output, there is a method `.display()` +which is compatible with the `format!()` parameter `{}`. This will render the +path as a string, replacing all non-utf8 sequences with the Replacement +Character (U+FFFD). As such it is not suitable for passing to any API that +actually operates on the path; it is only intended for display. + +## Example + +```rust +let mut path = Path::new("/tmp/path"); +debug2!("path: {}", path.display()); +path.set_filename("foo"); +path.push("bar"); +debug2!("new path: {}", path.display()); +let b = std::os::path_exists(&path); +debug2!("path exists: {}", b); +``` + +*/ + +use container::Container; +use c_str::CString; +use clone::Clone; +use fmt; +use iter::Iterator; +use option::{Option, None, Some}; +use str; +use str::{OwnedStr, Str, StrSlice}; +use to_str::ToStr; +use vec; +use vec::{CopyableVector, OwnedCopyableVector, OwnedVector, Vector}; +use vec::{ImmutableEqVector, ImmutableVector}; + +/// Typedef for POSIX file paths. +/// See `posix::Path` for more info. +pub use PosixPath = self::posix::Path; + +/// Typedef for Windows file paths. +/// See `windows::Path` for more info. +pub use WindowsPath = self::windows::Path; + +/// Typedef for the platform-native path type +#[cfg(unix)] +pub use Path = self::posix::Path; +/// Typedef for the platform-native path type +#[cfg(windows)] +pub use Path = self::windows::Path; + +/// Typedef for the platform-native component iterator +#[cfg(unix)] +pub use ComponentIter = self::posix::ComponentIter; +/// Typedef for the platform-native reverse component iterator +#[cfg(unix)] +pub use RevComponentIter = self::posix::RevComponentIter; +/// Typedef for the platform-native component iterator +#[cfg(windows)] +pub use ComponentIter = self::windows::ComponentIter; +/// Typedef for the platform-native reverse component iterator +#[cfg(windows)] +pub use RevComponentIter = self::windows::RevComponentIter; + +/// Typedef for the platform-native str component iterator +#[cfg(unix)] +pub use StrComponentIter = self::posix::StrComponentIter; +/// Typedef for the platform-native reverse str component iterator +#[cfg(unix)] +pub use RevStrComponentIter = self::posix::RevStrComponentIter; +/// Typedef for the platform-native str component iterator +#[cfg(windows)] +pub use StrComponentIter = self::windows::StrComponentIter; +/// Typedef for the platform-native reverse str component iterator +#[cfg(windows)] +pub use RevStrComponentIter = self::windows::RevStrComponentIter; + +/// Typedef for the platform-native separator char func +#[cfg(unix)] +pub use is_sep = self::posix::is_sep; +/// Typedef for the platform-native separator char func +#[cfg(windows)] +pub use is_sep = self::windows::is_sep; +/// Typedef for the platform-native separator byte func +#[cfg(unix)] +pub use is_sep_byte = self::posix::is_sep_byte; +/// Typedef for the platform-native separator byte func +#[cfg(windows)] +pub use is_sep_byte = self::windows::is_sep_byte; + +pub mod posix; +pub mod windows; + +// Condition that is raised when a NUL is found in a byte vector given to a Path function +condition! { + // this should be a &[u8] but there's a lifetime issue + null_byte: ~[u8] -> ~[u8]; +} + +/// A trait that represents the generic operations available on paths +pub trait GenericPath: Clone + GenericPathUnsafe { + /// Creates a new Path from a byte vector or string. + /// The resulting Path will always be normalized. + /// + /// # Failure + /// + /// Raises the `null_byte` condition if the path contains a NUL. + /// + /// See individual Path impls for additional restrictions. + #[inline] + fn new<T: BytesContainer>(path: T) -> Self { + if contains_nul(path.container_as_bytes()) { + let path = self::null_byte::cond.raise(path.container_into_owned_bytes()); + assert!(!contains_nul(path)); + unsafe { GenericPathUnsafe::new_unchecked(path) } + } else { + unsafe { GenericPathUnsafe::new_unchecked(path) } + } + } + + /// Creates a new Path from a byte vector or string, if possible. + /// The resulting Path will always be normalized. + #[inline] + fn new_opt<T: BytesContainer>(path: T) -> Option<Self> { + if contains_nul(path.container_as_bytes()) { + None + } else { + Some(unsafe { GenericPathUnsafe::new_unchecked(path) }) + } + } + + /// Returns the path as a string, if possible. + /// If the path is not representable in utf-8, this returns None. + #[inline] + fn as_str<'a>(&'a self) -> Option<&'a str> { + str::from_utf8_slice_opt(self.as_vec()) + } + + /// Returns the path as a byte vector + fn as_vec<'a>(&'a self) -> &'a [u8]; + + /// Converts the Path into an owned byte vector + fn into_vec(self) -> ~[u8]; + + /// Returns an object that implements `fmt::Default` for printing paths + /// + /// This will print the equivalent of `to_display_str()` when used with a {} format parameter. + fn display<'a>(&'a self) -> Display<'a, Self> { + Display{ path: self, filename: false } + } + + /// Returns an object that implements `fmt::Default` for printing filenames + /// + /// This will print the equivalent of `to_filename_display_str()` when used with a {} + /// format parameter.
