Struct WasmSourceMap 

pub struct WasmSourceMap {
    locations: BTreeMap<usize, SourceLocation>,
}

Source locations recovered from an input Wasm module’s DWARF sections.

Wasm DWARF addresses are relative to the beginning of the code-section payload, whereas FunctionBodyData offsets are relative to the complete module. This map performs that translation once before parallel codegen.

Fields

locations: BTreeMap<usize, SourceLocation>

Implementations

impl WasmSourceMap

pub fn new( module: &ModuleInfo, translation: &ModuleTranslationState, functions: &PrimaryMap<LocalFunctionIndex, FunctionBodyData<'_>>, ) -> Result<Self, String>

Build a source map for all local function operators in a module.

pub fn get(&self, wasm_offset: usize) -> Option<&SourceLocation>

Return the source location for a module-relative Wasm offset.

pub fn first_in_function( &self, body: &FunctionBodyData<'_>, ) -> Option<&SourceLocation>

Return the first mapped source location in a function body.

impl Default for WasmSourceMap

fn default() -> WasmSourceMap

Returns the “default value” for a type.
