From 54452cdd68a18b7caa8def20bbd587b769f4cb67 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Fri, 19 Dec 2014 08:57:12 -0800 Subject: std: Second pass stabilization for `ptr` This commit performs a second pass for stabilization over the `std::ptr` module. The specific actions taken were: * The `RawPtr` trait was renamed to `PtrExt` * The `RawMutPtr` trait was renamed to `MutPtrExt` * The module name `ptr` is now stable. * These functions were all marked `#[stable]` with no modification: * `null` * `null_mut` * `swap` * `replace` * `read` * `write` * `PtrExt::is_null` * `PtrExt::offset` * These functions remain unstable: * `as_ref`, `as_mut` - the return value of an `Option` is not fully expressive as null isn't the only bad value, and it's unclear whether we want to commit to these functions at this time. The reference/lifetime semantics as written are also problematic in how they encourage arbitrary lifetimes. * `zero_memory` - This function is currently not used at all in the distribution, and in general it plays a broader role in the "working with unsafe pointers" story. This story is not yet fully developed, so at this time the function remains unstable for now. * `read_and_zero` - This function remains unstable for largely the same reasons as `zero_memory`. * These functions are now all deprecated: * `PtrExt::null` - call `ptr::null` or `ptr::null_mut` instead. * `PtrExt::to_uint` - use an `as` expression instead. * `PtrExt::is_not_null` - use `!p.is_null()` instead. --- src/libstd/c_vec.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libstd/c_vec.rs') diff --git a/src/libstd/c_vec.rs b/src/libstd/c_vec.rs index f4338815f75..0aa51ee66ed 100644 --- a/src/libstd/c_vec.rs +++ b/src/libstd/c_vec.rs @@ -40,7 +40,7 @@ use mem; use ops::{Drop, FnOnce}; use option::Option; use option::Option::{Some, None}; -use ptr::RawPtr; +use ptr::PtrExt; use ptr; use raw; use slice::AsSlice; -- cgit 1.4.1-3-g733a5
