Struct swc_core::base::sourcemap::SourceView

pub struct SourceView { /* private fields */ }

Available on crate feature __base only.

Provides efficient access to minified sources.

This type is used to implement fairly efficient source mapping operations.

Implementations

impl SourceView

pub fn new(source: Arc<str>) -> SourceView

Creates an optimized view of a given source.

pub fn from_string(source: String) -> SourceView

Creates an optimized view from a given source string

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

Returns a requested minified line.

pub fn get_line_slice(&self, line: u32, col: u32, span: u32) -> Option<&str>

Returns a line slice.

Note that columns are indexed as JavaScript WTF-16 columns.

pub fn lines(&self) -> Lines<'_>

Returns an iterator over all lines.

pub fn source(&self) -> &str

Returns the source.

pub fn get_original_function_name<'map>( &self, token: Token<'map>, minified_name: &str ) -> Option<&'map str>

Given a token and minified function name this attemps to resolve the name to an original function name.

This invokes some guesswork and requires access to the original minified source. This will not yield proper results for anonymous functions or functions that do not have clear function names. (For instance it’s recommended that dotted function names are not passed to this function).

pub fn line_count(&self) -> usize

Returns the number of lines.

pub fn sourcemap_reference(&self) -> Result<Option<SourceMapRef>, Error>

Returns the source map reference in the source view.

Trait Implementations

impl Clone for SourceView

fn clone(&self) -> SourceView

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SourceView

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
