Struct ImplWithMetadata

struct ImplWithMetadata {
    attrs: ImplAttrs,
    implementation: ItemImpl,
    methods: Vec<TraitItemFn>,
    generics: Generics,
    abi: TraitAbiMetadata,
}

Expand description

Populated impl plus declaration metadata, supplied by the trait’s macro. Keep this as Rust syntax so method bodies, generics and author attributes pass through without a second bespoke representation.

impl<T> SizeHint for T
where T: ?Sized,

Source §

default fn lower_bound(&self) -> usize

🔬This is a nightly-only experimental API. (core_io_internals)

Returns a lower bound on the number of elements this container-like item contains. For example, an array [u8; 12] could return any value between 0 and 12 inclusively as a correct implementation. Read more

default fn upper_bound(&self) -> Option<usize>

🔬This is a nightly-only experimental API. (core_io_internals)

Returns an upper bound on the number of elements this container-like item contains if it can be determined, otherwise None. Read more

Source §

final fn size_hint(&self) -> (usize, Option<usize>)

🔬This is a nightly-only experimental API. (core_io_internals)
