Struct sourcemap::Token

pub struct Token<'a> { /* fields omitted */ }

Represents a token from a sourcemap

Methods

impl<'a> Token<'a>

fn get_dst_line(&self) -> u32

get the destination (minified) line number

fn get_dst_col(&self) -> u32

get the destination (minified) column number

fn get_dst(&self) -> (u32, u32)

get the destination line and column

fn get_src_line(&self) -> u32

get the source line number

fn get_src_col(&self) -> u32

get the source column number

fn get_src(&self) -> (u32, u32)

get the source line and column

fn get_src_id(&self) -> u32

Return the source ID of the token

fn get_source(&self) -> Option<&'a str>

get the source if it exists as string

fn has_source(&self) -> bool

Is there a source for this token?

fn get_name(&self) -> Option<&'a str>

get the name if it exists as string

fn has_name(&self) -> bool

returns true if a name exists, false otherwise

fn get_name_id(&self) -> u32

Return the name ID of the token

fn get_minified_name<'b>(&self, source: &'b str) -> Option<&'b str>

Given some minified source this returns the most likely minified name.

Note that this scans for identifiers in the source file so in some cases it can happen that values are returned that are not actually names. For instance a token that points to a keyword will return the keyword. This is done because it is not always possible to tell keywords from non keywords without parsing the entire source.

fn to_tuple(&self) -> (&'a str, u32, u32, Option<&'a str>)

Converts the token into a debug tuple in the form (source, src_line, src_col, name)

fn get_raw_token(&self) -> RawToken

Get the underlying raw token

Trait Implementations

impl<'a> Copy for Token<'a>
