Struct Span

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

Span represents a range of a piece of source code. It counts by offset, so it’s 0-based.

Fields

start: usize

Start offset. (Inclusive)

end: usize

End offset. (Exclusive)

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl Hash for Span

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 Span

fn eq(&self, other: &Span) -> 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.

impl SpanIgnoredEq for Span

fn span_ignored_eq(&self, _: &Self) -> bool

Compare equality of two AST nodes without respecting their spans.

impl Eq for Span

impl StructuralPartialEq for Span
