Struct rustc_ap_rustc_span::SourceFile [−][src]
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.
src: Option<Lrc<String>>
The complete source code.
src_hash: SourceFileHash
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.
cnum: CrateNum
Indicates which crate this SourceFile
was imported from.
Implementations
impl SourceFile
[src]
pub fn new(
name: FileName,
name_was_remapped: bool,
unmapped_path: FileName,
src: String,
start_pos: BytePos,
hash_kind: SourceFileHashAlgorithm
) -> Self
[src]
name: FileName,
name_was_remapped: bool,
unmapped_path: FileName,
src: String,
start_pos: BytePos,
hash_kind: SourceFileHashAlgorithm
) -> Self
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 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) -> Range<BytePos>
[src]
pub fn contains(&self, byte_pos: BytePos) -> bool
[src]
Returns whether or not the file contains the given SourceMap
byte
position. The position one past the end of the file is considered to be
contained by the file. This implies that files for which is_empty
returns true still contain one byte position according to this function.
pub fn is_empty(&self) -> 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.
pub fn bytepos_to_file_charpos(&self, bpos: BytePos) -> CharPos
[src]
Converts an absolute BytePos
to a CharPos
relative to the SourceFile
.
pub fn lookup_file_pos(&self, pos: BytePos) -> (usize, CharPos)
[src]
Looks up the file’s (1-based) line number and (0-based CharPos
) column offset, for a
given BytePos
.
pub fn lookup_file_pos_with_col_display(
&self,
pos: BytePos
) -> (usize, CharPos, usize)
[src]
&self,
pos: BytePos
) -> (usize, CharPos, usize)
Looks up the file’s (1-based) line number, (0-based CharPos
) column offset, and (0-based)
column offset when displayed, for a given BytePos
.
