Struct SourceMap 

pub struct SourceMap<UL> {
    pub mappings: HashMap<SourceMapLocation, UL>,
}

What each place in a script came from in the original source.

UL is whatever the frontend wants to point at: a line and column, a file name, a node id in a graph. A frontend fills this in while it produces the script, and a debugger reads it back.

Fields

mappings: HashMap<SourceMapLocation, UL>

Source location of each place in the script.

Implementations

impl<UL> SourceMap<UL>

pub fn map(&self, location: SourceMapLocation) -> Option<&UL>

Returns what location came from, or None when it was never mapped.

Trait Implementations

where UL: Clone,

fn clone(&self) -> SourceMap<UL>

Formats the value using the given formatter.

impl<UL> Default for SourceMap<UL>

where UL: Default,

fn default() -> SourceMap<UL>

Returns the “default value” for a type.
