Struct SourceMap 

pub struct SourceMap {
    pub sources: Vec<SourceFile>,
    pub entries: Vec<SourceMapEntry>,
}

Maps layout nodes to regions in source input files.

Fields

sources: Vec<SourceFile>

Registered source files.

entries: Vec<SourceMapEntry>

Node to source relationships. A node may have multiple entries.

Implementations

impl SourceMap

pub fn add_source(&mut self, name: impl Into<String>) -> SourceId

Registers a new source file by name and returns its identifier.

pub fn intern_source(&mut self, name: impl Into<String>) -> SourceId

Returns the existing source identifier for a name, or registers a new one.

pub fn add_entry(&mut self, node: NodeId, range: SourceRange, role: SourceRole)

Appends a source map entry linking a node to a source range.

pub fn source(&self, id: SourceId) -> Option<&SourceFile>

Returns the source file for the given identifier.

pub fn entries_for_node( &self, node: NodeId, ) -> impl Iterator<Item = &SourceMapEntry>

Iterates all entries for the given node.

pub fn primary_range_for_node(&self, node: NodeId) -> Option<SourceRange>

Returns the primary source range for the given node, if present.

Trait Implementations

impl Clone for SourceMap

fn clone(&self) -> SourceMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceMap

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

Formats the value using the given formatter.

impl Default for SourceMap

fn default() -> SourceMap

Returns the “default value” for a type.

impl Eq for SourceMap

impl PartialEq for SourceMap

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