error[E0599]: the method `as_display` exists for reference `&NoDisplay`, but its trait bounds were not satisfied
|
|
--> tests/ui/no-display.rs:7:9
|
|
|
|
|
4 | struct NoDisplay;
|
|
| ---------------- doesn't satisfy `NoDisplay: std::fmt::Display`
|
|
...
|
|
7 | #[error("thread: {thread}")]
|
|
| ^^^^^^^^^^^^^^^^^^ method cannot be called on `&NoDisplay` due to unsatisfied trait bounds
|
|
|
|
|
= note: the following trait bounds were not satisfied:
|
|
`NoDisplay: std::fmt::Display`
|
|
which is required by `&NoDisplay: AsDisplay<'_>`
|
|
note: the trait `std::fmt::Display` must be implemented
|
|
--> $RUST/core/src/fmt/mod.rs
|
|
|
|
|
| pub trait Display {
|
|
| ^^^^^^^^^^^^^^^^^
|
|
= help: items from traits can only be used if the trait is implemented and in scope
|
|
= note: the following trait defines an item `as_display`, perhaps you need to implement it:
|
|
candidate #1: `AsDisplay`
|
|
|
|
error[E0277]: the trait bound `NoDisplay: Octal` is not satisfied
|
|
--> tests/ui/no-display.rs:13:9
|
|
|
|
|
12 | #[derive(Error, Debug)]
|
|
| ----- in this derive macro expansion
|
|
13 | #[error("thread: {thread:o}")]
|
|
| ^^^^^^^^^^^^^^^^^^^^ the trait `Octal` is not implemented for `NoDisplay`
|
|
|
|
|
= help: the following other types implement trait `Octal`:
|
|
&T
|
|
&mut T
|
|
NonZero<T>
|
|
Saturating<T>
|
|
Wrapping<T>
|
|
i128
|
|
i16
|
|
i32
|
|
and $N others
|
|
= note: required for `&NoDisplay` to implement `Octal`
|
|
note: required by a bound in `core::fmt::rt::Argument::<'_>::new_octal`
|
|
--> $RUST/core/src/fmt/rt.rs
|
|
|
|
|
| pub fn new_octal<T: Octal>(x: &T) -> Argument<'_> {
|
|
| ^^^^^ required by this bound in `Argument::<'_>::new_octal`
|
|
= note: this error originates in the macro `$crate::format_args` which comes from the expansion of the derive macro `Error` (in Nightly builds, run with -Z macro-backtrace for more info)
