Struct SourceMap 

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

Source files and the enclosing construct spans of nodes.

Fields

sources: Vec<SourceFile>

Registered source files, sources[i].id == SourceId(i).

entries: Vec<SourceMapEntry>

Enclosing construct spans, innermost first per node.

Implementations

impl SourceMap

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

Registers a source file and returns its id.

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

Returns the id of a source file by name, registering it when new.

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

Records an enclosing construct span of a node.

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

Returns a registered source file.

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

Iterates the enclosing construct entries of a node.
