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.

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)

Performs copy-assignment from source.

impl Debug for Limit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Limit

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Div<usize> for Limit

type Output = Limit

The resulting type after applying the / operator.

fn div(self, rhs: usize) -> Self::Output

Performs the / operation.

impl From<usize> for Limit

fn mul(self, rhs: usize) -> Self::Output

Performs the * operation.

impl Copy for Limit

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.
