Struct Span 

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

Represents a range in source code from a start position to an end position.

Used to track the location of tokens, expressions, and errors in the source.

Fields

start: Position

end: Position

Implementations

impl Span

pub fn new(start: Position, end: Position) -> Self

pub fn single(pos: Position) -> Self

Creates a span that covers a single position (zero-width span).

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 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 Copy for Span
