A single source in the SourceMap.

Fields

name: FileName

The name of the file that the source came from. Source that doesn't originate from files has names between angle brackets by convention (e.g., <anon>).

name_was_remapped: bool

true if the name field above has been modified by --remap-path-prefix.

unmapped_path: Option<FileName>

The unmapped path of the file that the source came from. Set to None if the SourceFile was imported from an external crate.

crate_of_origin: u32

Indicates which crate this SourceFile was imported from.

src: Option<Lrc<String>>

The complete source code.

src_hash: u128

The source code's hash.

external_src: Lock<ExternalSource>

The external source code (used for external crates, which will have a None value as self.src.

start_pos: BytePos

The start position of this source in the SourceMap.

end_pos: BytePos

The end position of this source in the SourceMap.

lines: Vec<BytePos>

Locations of lines beginnings in the source code.

multibyte_chars: Vec<MultiByteChar>

Locations of multi-byte characters in the source code.

non_narrow_chars: Vec<NonNarrowChar>

Width of characters that are not narrow in the source code.

normalized_pos: Vec<NormalizedPos>

Locations of characters removed during normalization.

name_hash: u128

A hash of the filename, used for speeding up hashing in incremental compilation.

Methods

impl SourceFile[src]

pub fn new(
    name: FileName,
    name_was_remapped: bool,
    unmapped_path: FileName,
    src: String,
    start_pos: BytePos
) -> Self
[src]

pub fn line_begin_pos(&self, pos: BytePos) -> BytePos[src]

Returns the BytePos of the beginning of the current line.

pub fn add_external_src<F>(&self, get_src: F) -> bool where
    F: FnOnce() -> Option<String>, 
[src]

Add externally loaded source. If the hash of the input doesn't match or no input is supplied via None, it is interpreted as an error and the corresponding enum variant is set. The return value signifies whether some kind of source is present.

pub fn get_line(&self, line_number: usize) -> Option<Cow<str>>[src]

Gets a line from the list of pre-computed line-beginnings. The line number here is 0-based.

pub fn is_real_file(&self) -> bool[src]

pub fn is_imported(&self) -> bool[src]

pub fn byte_length(&self) -> u32[src]

pub fn count_lines(&self) -> usize[src]

pub fn lookup_line(&self, pos: BytePos) -> Option<usize>[src]

Finds the line containing the given position. The return value is the index into the lines array of this SourceFile, not the 1-based line number. If the source_file is empty or the position is located before the first line, None is returned.

pub fn line_bounds(&self, line_index: usize) -> (BytePos, BytePos)[src]

pub fn contains(&self, byte_pos: BytePos) -> bool[src]

pub fn original_relative_byte_pos(&self, pos: BytePos) -> BytePos[src]

Calculates the original byte position relative to the start of the file based on the given byte position.
