Struct Limit

pub struct Limit(pub usize);

New-type wrapper around usize for representing limits. Ensures that comparisons against limits are consistent throughout the compiler.

Tuple Fields

0: usize

Implementations

impl Limit

pub fn new(value: usize) -> Self

Create a new limit from a usize.

pub fn value_within_limit(&self, value: usize) -> bool

Check that value is within the limit. Ensures that the same comparisons are used throughout the compiler, as mismatches can cause ICEs, see #72540.

Trait Implementations

impl Clone for Limit

fn clone(&self) -> Limit

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
