Struct Range 

pub struct Range {
    pub start: Point,
    pub end: Point,
}

The stretch of the function a value is live over.

Both ends are included: a value written at a point and read at a later one is live at both, and one written and never read is live at the single point that wrote it, because the register it was written to is not free at the instant it was written to.

Fields

start: Point

Where the value is written.

end: Point

The last place it is read, or where it is written if nothing reads it.

Implementations

impl Range

pub fn covers(self, point: Point) -> bool

Whether the value is live at that point.

pub fn overlaps(self, other: Self) -> bool

Whether two values are both live anywhere, which is what stops them sharing a register.

Trait Implementations
