[−][src]Struct syntax::source_map::SourceFile
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<Rc<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.
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
) -> SourceFile
[src]
name: FileName,
name_was_remapped: bool,
unmapped_path: FileName,
src: String,
start_pos: BytePos
) -> SourceFile
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]
F: FnOnce() -> Option<String>,
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]
