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

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.

Implementations§

source§

impl WrappingRange

source

pub fn full(size: Size) -> Self

source

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