error[E0282]: type annotations needed for `Vec<T>`
--> $DIR/method-ambig-one-trait-unknown-int-type.rs:24:9
|
LL | let mut x = Vec::new();
| ^^^^^
|
help: consider giving `x` an explicit type, where the type for type parameter `T` is specified
|
LL | let mut x: Vec<T> = Vec::new();
| ++++++++
error[E0283]: type annotations needed
--> $DIR/method-ambig-one-trait-unknown-int-type.rs:26:7
|
LL | x.foo();
| ^^^
|
note: multiple `impl`s satisfying `Vec<_>: Foo` found
--> $DIR/method-ambig-one-trait-unknown-int-type.rs:9:1
|
LL | impl Foo for Vec<usize> {
| ^^^^^^^^^^^^^^^^^^^^^^^
...
LL | impl Foo for Vec<isize> {
| ^^^^^^^^^^^^^^^^^^^^^^^
help: try using a fully qualified path to specify the expected types
|
LL | <Vec<T> as Foo>::foo(&x);

error[E0308]: mismatched types
--> $DIR/method-ambig-one-trait-unknown-int-type.rs:33:20
|
LL | let y: usize = x.foo();
| ----- ^^^^^^^ expected `usize`, found `isize`
| |
| expected due to this
|
help: you can convert an `isize` to a `usize` and panic if the converted value doesn't fit
|
LL | let y: usize = x.foo().try_into().unwrap();
| ++++++++++++++++++++
