Struct SourceSpan 

pub struct SourceSpan {
    pub start_inclusive: SourcePosition,
    pub end_exclusive: SourcePosition,
    pub file_path: Option<PathBuf>,
}

Represents a span of source text from start to end position.

The span is a half-open interval: [start_inclusive, end_exclusive).

• start_inclusive: Position of the first character of the source text
• end_exclusive: Position immediately after the last character

Optionally includes a file path for the referenced source text.

Fields

start_inclusive: SourcePosition

end_exclusive: SourcePosition

file_path: Option<PathBuf>

The file path to the source text this span refers to, if available.

Implementations

impl SourceSpan

pub fn line_col(&self) -> ((u32, u32), (u32, u32))

Returns ((start_line, start_col), (end_line, end_col)) as 0-based u32 tuples.

Delegates to SourcePosition::line_col() on both endpoints.

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

Creates a span without file path information.

pub fn with_file( start: SourcePosition, end: SourcePosition, file_path: PathBuf, ) -> Self

Creates a span with file path information.

pub fn zero() -> Self

Creates a zero-position span with no file path.

Used as a fallback when source position resolution is unavailable (e.g. errors constructed without a SourceMap).

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.
