Struct WrappingRange

pub struct WrappingRange {
    pub start: u128,
    pub end: u128,
}

Inclusive wrap-around range of valid values, that is, if start > end, it represents start..=MAX, followed by 0..=end.

That is, for an i8 primitive, a range of 254..=2 means following sequence:

254 (-2), 255 (-1), 0, 1, 2

This is intended specifically to mirror LLVM’s !range metadata semantics.

Fields

start: u128

end: u128

Implementations

impl WrappingRange

pub fn full(size: Size) -> Self

pub fn contains(&self, v: u128) -> bool

Returns true if v is contained in the range.

Trait Implementations

impl Clone for WrappingRange

fn clone(&self) -> WrappingRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrappingRange

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

Formats the value using the given formatter.

impl Hash for WrappingRange

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WrappingRange

fn eq(&self, other: &WrappingRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
