    // some fields omitted
}

Fields

files: RefCell<Vec<Rc<FileMap>>>

Methods

impl CodeMap

pub fn new(path_mapping: FilePathMapping) -> CodeMap

pub fn with_file_loader(
    file_loader: Box<dyn FileLoader>,
    path_mapping: FilePathMapping
) -> CodeMap

pub fn path_mapping(&self) -> &FilePathMapping

pub fn file_exists(&self, path: &Path) -> bool

pub fn load_file(&self, path: &Path) -> Result<Rc<FileMap>>

pub fn files(&self) -> Ref<Vec<Rc<FileMap>>>

pub fn new_filemap(&self, filename: FileName, src: String) -> Rc<FileMap>

Creates a new filemap without setting its line information. If you don't intend to set the line information yourself, you should use new_filemap_and_lines.

pub fn new_filemap_and_lines(&self, filename: &str, src: &str) -> Rc<FileMap>

Creates a new filemap and sets its line information.

pub fn new_imported_filemap(
    &self,
    filename: FileName,
    name_was_remapped: bool,
    crate_of_origin: u32,
    source_len: usize,
    file_local_lines: Vec<BytePos>,
    file_local_multibyte_chars: Vec<MultiByteChar>
) -> Rc<FileMap>

Allocates a new FileMap representing a source file from an external crate. The source code of such an "imported filemap" is not available, but we still know enough to generate accurate debuginfo location information for things inlined from other crates.

pub fn mk_substr_filename(&self, sp: Span) -> String

pub fn lookup_char_pos(&self, pos: BytePos) -> Loc

Lookup source information about a BytePos

pub fn lookup_char_pos_adj(&self, pos: BytePos) -> LocWithOpt

pub fn merge_spans(&self, sp_lhs: Span, sp_rhs: Span) -> Option<Span>

Returns Some(span), a union of the lhs and rhs span. The lhs must precede the rhs. If there are gaps between lhs and rhs, the resulting union will cross these gaps. For this to work, the spans have to be:

• the ctxt of both spans much match
• the lhs span needs to end on the same line the rhs span begins
• the lhs span must start at or before the rhs span

pub fn span_to_string(&self, sp: Span) -> String

pub fn span_to_filename(&self, sp: Span) -> FileName

pub fn span_to_lines(&self, sp: Span) -> FileLinesResult

pub fn span_to_snippet(&self, sp: Span) -> Result<String, SpanSnippetError>

pub fn span_until_char(&self, sp: Span, c: char) -> Span

Given a Span, try to get a shorter span ending before the first occurrence of c char

pub fn def_span(&self, sp: Span) -> Span

pub fn get_filemap(&self, filename: &str) -> Option<Rc<FileMap>>

pub fn lookup_byte_offset(&self, bpos: BytePos) -> FileMapAndBytePos

For a global BytePos compute the local offset within the containing FileMap

pub fn bytepos_to_file_charpos(&self, bpos: BytePos) -> CharPos

Converts an absolute BytePos to a CharPos relative to the filemap.

pub fn lookup_filemap_idx(&self, pos: BytePos) -> usize

pub fn count_lines(&self) -> usize
