Trait Implementations

impl Clone for CodeMap

fn clone(&self) -> CodeMap

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CodeMap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CodeMap

fn default() -> CodeMap

Returns the "default value" for a type.

impl<'a> Files<'a> for CodeMap

type FileId = FileId

A unique identifier for files in the file provider. This will be used for rendering diagnostic::Labels in the corresponding source files.

type Name = String

The user-facing name of a file, to be displayed in diagnostics.

type Source = &'a str

The source code of a file.

fn name(&self, file_id: FileId) -> Option<Self::Name>

The user-facing name of a file.

fn source(&self, file_id: FileId) -> Option<&str>

The source code of a file.

fn line_index(&self, file_id: FileId, byte_index: usize) -> Option<usize>

The index of the line at the given byte index.

fn line_range(&self, file_id: FileId, line_index: usize) -> Option<Range<usize>>

The byte range of line in the source of the file.

fn line_number(&'a self, id: Self::FileId, line_index: usize) -> Option<usize>

The user-facing line number at the given line index.

fn column_number(
    &'a self,
    id: Self::FileId,
    line_index: usize,
    byte_index: usize
) -> Option<usize>

The user-facing column number at the given line index and byte index.

fn location(&'a self, id: Self::FileId, byte_index: usize) -> Option<Location>

Convenience method for returning line and column number at the given a byte index in the file.
