[−][src]Enum sourcemap::DecodedMap

pub enum DecodedMap {
    Regular(SourceMap),
    Index(SourceMapIndex),
}

Represents the result of a decode operation

This represents either an actual sourcemap or a source map index. Usually the two things are too distinct to provide a common interface however for token lookup and writing back into a writer general methods are provided.

Variants

Regular(SourceMap)

Indicates a regular sourcemap

Index(SourceMapIndex)

Indicates a sourcemap index

Methods

impl DecodedMap[src]

pub fn from_reader<R: Read>(rdr: R) -> Result<DecodedMap>[src]

Alias for decode.

pub fn to_writer<W: Write>(&self, w: W) -> Result<()>[src]

Writes a decoded sourcemap to a writer.

pub fn lookup_token(&self, line: u32, col: u32) -> Option<Token>[src]

Shortcut to look up a token on either an index or a regular sourcemap. This method can only be used if the contained index actually contains embedded maps or it will not be able to look up anything.
