Struct MapHint

#[non_exhaustive]
pub struct MapHint {
    pub size: usize,
}

A hint passed in when encoding a map.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

size: usize

The size for the map being encoded.

Implementations

impl MapHint

pub const fn with_size(size: usize) -> Self

Create a new struct hint with the specified size.

Examples

use musli::hint::MapHint;

static HINT: MapHint = MapHint::with_size(16);

assert_eq!(HINT.size, 16);

pub fn size_hint(&self) -> SizeHint

Return the size hint that corresponds to this overall hint.
