Trait AliasExpandError

pub trait AliasExpandError: Sized {
    // Required methods
    fn invalid_arguments(err: InvalidArguments<'_>) -> Self;
    fn recursive_expansion(id: AliasId<'_>, span: Span<'_>) -> Self;
    fn within_alias_expansion(self, id: AliasId<'_>, span: Span<'_>) -> Self;
}

Error that may occur during alias substitution.

Required Methods

fn invalid_arguments(err: InvalidArguments<'_>) -> Self

Unexpected number of arguments, or invalid combination of arguments.

fn recursive_expansion(id: AliasId<'_>, span: Span<'_>) -> Self

Recursion detected during alias substitution.

fn within_alias_expansion(self, id: AliasId<'_>, span: Span<'_>) -> Self

Attaches alias trace to the current error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
