Struct SourceMapView

pub struct SourceMapView { /* private fields */ }

Represents a source map.

Implementations

impl SourceMapView

pub fn from_json_slice(buffer: &[u8]) -> Result<Self, ParseSourceMapError>

Constructs a sourcemap from a slice.

If the sourcemap is an index it is being flattened. If flattening is not possible then an error is raised.

pub fn lookup_token(&self, line: u32, col: u32) -> Option<TokenMatch<'_>>

Looks up a token and returns it.

pub fn get_token(&self, idx: u32) -> Option<TokenMatch<'_>>

Returns a token for a specific index.

pub fn get_token_count(&self) -> u32

Returns the number of tokens.

pub fn get_source_view(&self, idx: u32) -> Option<&SourceView<'_>>

Returns a source view for the given source.

pub fn get_source_name(&self, idx: u32) -> Option<&str>

Returns the source name for an index.

pub fn get_source_count(&self) -> u32

Returns the number of sources.

pub fn lookup_token_with_function_name<'a, 'b>( &'a self, line: u32, col: u32, minified_name: &str, source: &SourceView<'b>, ) -> Option<TokenMatch<'a>>

Looks up a token and the original function name.

This is similar to lookup_token but if a minified function name and the sourceview to the minified source is available this function will also resolve the original function name. This is used to fully resolve tracebacks.
