Struct Span

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

Represents a [start, end) span for a source expression.

Fields

start: usize

The start of the span, inclusive.

end: usize

The end of the span, exclusive.

Implementations

impl Span

pub fn adjust(self, bias: usize) -> Self

Adjust this span by the given bias.

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

Returns a duplicate of the value.

const 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 From<Range<usize>> for Span

fn from(range: Range<usize>) -> Self

Converts to this type from the input type.

impl From<Span<'_>> for Span

fn from(span: Span<'_>) -> Self

Converts to this type from the input type.

impl From<Span> for Range<usize>

fn from(span: Span) -> Self

Converts to this type from the input type.

impl PartialEq for Span

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

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

const 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 Copy for Span
