Struct SourceSpan

pub struct SourceSpan { /* private fields */ }

The source location of a parsed node: file ID and text range (start and end byte offsets) within that file.

Implementations

impl SourceSpan

pub fn file_id(&self) -> FileId

Returns the file ID for this location

pub fn offset(&self) -> usize

Returns the offset from the start of the file to the start of the range, in UTF-8 bytes

pub fn end_offset(&self) -> usize

Returns the offset from the start of the file to the end of the range, in UTF-8 bytes

pub fn node_len(&self) -> usize

Returns the length of the range, in UTF-8 bytes

pub fn recompose(start_of: Option<Self>, end_of: Option<Self>) -> Option<Self>

Best effort at making a location with the given start and end

pub fn line_column(&self, sources: &SourceMap) -> Option<LineColumn>

The line and column numbers of Self::offset

pub fn line_column_range( &self, sources: &SourceMap, ) -> Option<Range<LineColumn>>

The line and column numbers of the range from Self::offset to Self::end_offset inclusive.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate of the value.

const 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 Hash for SourceSpan

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
