Struct Span

pub struct Span {
    pub start: Location,
    pub end: Location,
}

A span is a pair of Locations that represent a range in the source text.

The start location is inclusive, and the end location is exclusive. A span with the same start and end location is considered empty.

Fields

start: Location

end: Location

Implementations

impl Span

pub fn new(range: Range<Location>) -> Self

Creates a new span from a range of Locations. The range must be valid, i.e. the start location must be less than or equal to the end location.

Panics

In debug builds, panics if the range is invalid.

pub fn contains_loc(&self, loc: Location) -> bool

Whether the span contains the given Location.

pub fn contains(&self, other: &Span) -> bool

Whether the span fully contains the given span. This includes the case where the spans are equal.

pub fn is_empty(&self) -> bool

Whether the span is empty.
