Struct rustc_session::session::Limit

pub struct Limit(pub usize);

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

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.
