UnpackedSourceMap
A source map that supports efficient mapping queries.
This bundles together a SourceMap and a cache of its unpacked mapping segments.
Topics
Initializers
init(SourceMap)
init(SourceMap)
Unpack a new source map and cache the segments.
Declaration
public init(_ sourceMap: SourceMap) throwsMethods
func map(line: Int, column: Int, invalidSourcePos: SourceMap.SourcePos?) -> SourceMap.Segment?
func map(line: Int, column: Int, invalidSourcePos: SourceMap.SourcePos?) -> SourceMap.Segment?
Map a location in the generated code to its source.
All name indices are guaranteed valid at time of call: any out of range are replaced with
nil before being returned. All source indices are either valid at time of call or as
requested via the invalidSourcePos parameter.
Declaration
public func map(
line: Int, column: Int, invalidSourcePos: SourceMap.SourcePos? = nil
) -> SourceMap.Segment?Parameters
line |
0-based index of the line in the generated code file. |
column |
0-based index of the column in |
invalidSourcePos |
Value to substitute for any decoded |
Return Value
The mapping segment, or nil if there is no mapping for the row.
