Struct SourceMapBuilder 

pub struct SourceMapBuilder { /* private fields */ }

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.

Implementations

impl SourceMapBuilder

pub fn new(file: Option<BytesStr>) -> SourceMapBuilder

Creates a new source map builder and sets the file.

pub fn set_debug_id(&mut self, debug_id: Option<DebugId>)

Sets the debug id for the sourcemap (optional)

pub fn set_file<T: Into<BytesStr>>(&mut self, value: Option<T>)

Sets the file for the sourcemap (optional)

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

Returns the currently set file.

pub fn set_source_root<T: Into<BytesStr>>(&mut self, value: Option<T>)

Sets a new value for the source_root.

pub fn get_source_root(&self) -> Option<&str>

Returns the embedded source_root in case there is one.

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

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

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

Changes the source name for an already set source.

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

Looks up a source name for an ID.

pub fn add_to_ignore_list(&mut self, src_id: u32)

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

Sets the source contents for an already existing source.

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

Returns the current source contents for a source.

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

Checks if a given source ID has source contents available.

pub 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

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

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

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

Adds a new mapping to the builder.

pub fn add_raw( &mut self, dst_line: u32, dst_col: u32, src_line: u32, src_col: u32, source: Option<u32>, name: Option<u32>, is_range: bool, ) -> RawToken

Adds a new mapping to the builder.

pub 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.

pub fn strip_prefixes<S: AsRef<str>>(&mut self, prefixes: &[S])

Strips common prefixes from the sources in the builder

pub fn into_sourcemap(self) -> SourceMap

Converts the builder into a sourcemap.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
