Struct Span 

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

A span in the source code (byte offsets).

Fields

start: usize

Start byte offset (inclusive).

end: usize

End byte 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 From<Range<usize>> for Span

fn from(range: Range<usize>) -> 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 ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
