Struct sourcemap::SourceMapBuilder

pub struct SourceMapBuilder { /* fields omitted */ }

Helper for sourcemap generation

This helper exists because generating and modifying SourceMap objects is generally not very comfortable. As a general aid this type can help.

Methods

impl SourceMapBuilder

fn new(file: Option<&str>) -> SourceMapBuilder

Creates a new source map builder and sets the file.

fn set_file(&mut self, value: Option<&str>)

Sets the file for the sourcemap (optional)

fn get_file(&self) -> Option<&str>

Returns the currently set file.

fn add_source(&mut self, src: &str) -> u32

Registers a new source with the builder and returns the source ID.

fn set_source(&mut self, src_id: u32, src: &str)

Changes the source name for an already set source.

fn get_source(&self, src_id: u32) -> Option<&str>

Looks up a source name for an ID.

fn set_source_contents(&mut self, src_id: u32, contents: Option<&str>)

Sets the source contents for an already existing source.

fn get_source_contents(&self, src_id: u32) -> Option<&str>

Returns the current source contents for a source.

fn has_source_contents(&self, src_id: u32) -> bool

Checks if a given source ID has source contents available.

fn load_local_source_contents(&mut self,
                              base_path: Option<&Path>)
                              -> Result<usize>

Loads source contents from locally accessible files if referenced accordingly. Returns the number of loaded source contents

fn add_name(&mut self, name: &str) -> u32

Registers a name with the builder and returns the name ID.

fn add(&mut self,
       dst_line: u32,
       dst_col: u32,
       src_line: u32,
       src_col: u32,
       source: Option<&str>,
       name: Option<&str>)
       -> RawToken

Adds a new mapping to the builder.

fn add_token(&mut self, token: &Token, with_name: bool) -> RawToken

Shortcut for adding a new mapping based of an already existing token, optionally removing the name.

fn into_sourcemap(self) -> SourceMap

Converts the builder into a sourcemap.
