error[E0005]: refutable pattern in local binding
--> $DIR/const-pat-non-exaustive-let-new-var.rs:4:9
|
LL | let A = 3;
| ^ patterns `i32::MIN..=1_i32` and `3_i32..=i32::MAX` not covered
...
LL | const A: i32 = 2;
| ------------ missing patterns are not covered because `A` is interpreted as a constant pattern, not a new variable
|
= note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant
= note: for more information, visit https://doc.rust-lang.org/book/ch19-02-refutability.html
= note: the matched value is of type `i32`
help: introduce a variable instead
|
LL | let A_var = 3;
