Struct codespan::FileMap

pub struct FileMap { /* fields omitted */ }

Some source code

Methods

impl FileMap

pub fn new(name: FileName, src: String) -> FileMap

Construct a new, standalone filemap.

This can be useful for tests that consist of a single source file. Production code should however use CodeMap::add_filemap or CodeMap::add_filemap_from_disk instead.

pub fn name(&self) -> &FileName

The name of the file that the source came from

pub fn src(&self) -> &str

The underlying source code

pub fn span(&self) -> ByteSpan

The span of the source in the CodeMap

pub fn offset(
    &self,
    line: LineIndex,
    column: ColumnIndex
) -> Result<ByteOffset, LocationError>

pub fn byte_index(
    &self,
    line: LineIndex,
    column: ColumnIndex
) -> Result<ByteIndex, LocationError>

pub fn line_offset(
    &self,
    index: LineIndex
) -> Result<ByteOffset, LineIndexError>

Returns the byte offset to the start of line

pub fn line_byte_index(
    &self,
    index: LineIndex
) -> Result<ByteIndex, LineIndexError>

Returns the byte index of the start of line

pub fn line_span(&self, line: LineIndex) -> Result<ByteSpan, LineIndexError>

Returns the byte offset to the start of line

pub fn location(
    &self,
    index: ByteIndex
) -> Result<(LineIndex, ColumnIndex), ByteIndexError>

Returns the line and column location of byte

pub fn find_line(&self, index: ByteIndex) -> Result<LineIndex, ByteIndexError>

Returns the line index that the byte index points to

pub fn src_slice(&self, span: ByteSpan) -> Result<&str, SpanError>

Get the corresponding source string for a span

Returns Err if the span is outside the bounds of the file

Trait Implementations

impl Debug for FileMap

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
