Struct SourceSpan 

pub struct SourceSpan {
    pub byte_start: usize,
    pub byte_end: usize,
    pub line: usize,
    pub column: usize,
}

Byte and line/column location for source-backed items.

Fields

byte_start: usize

Byte offset where the item starts.

byte_end: usize

Byte offset where the item ends.

line: usize

Line number where the item starts (1-indexed).

column: usize

Column number where the item starts (1-indexed).

Implementations

impl SourceSpan

pub const fn new( byte_start: usize, byte_end: usize, line: usize, column: usize, ) -> Self

Create a new source span.

pub const fn len(self) -> usize

Return the byte length covered by this span.

pub const fn is_empty(self) -> bool

Return true when the span is empty.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceSpan

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

Formats the value using the given formatter.

impl PartialEq for SourceSpan

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