Struct FileSpan

pub struct FileSpan { /* private fields */ }

A type representing a single line of a [Source].

Implementations

impl FileSpan

pub fn new(file: FileID, start: usize, end: usize) -> FileSpan

Create a new span with the given start and end offsets, and the given file.

pub fn get_range(&self) -> Range<usize>

Create a new span with the given start and end offsets, and the given file.

pub fn get_start(&self) -> usize

Get the start offset of this span.

Offsets are zero-indexed character offsets from the beginning of the source.

pub fn get_end(&self) -> usize

Get the (exclusive) end offset of this span.

The end offset should always be greater than or equal to the start offset as given by [Span::start].

Offsets are zero-indexed character offsets from the beginning of the source.

pub fn set_range(&mut self, range: Range<usize>)

Create a new span with the given start and end offsets, and the given file.

pub fn with_range(self, range: Range<usize>) -> FileSpan

Create a new span with the given start and end offsets, and the given file.

pub fn get_file(&self) -> FileID

Create a new span with the given start and end offsets, and the given file.

pub fn set_file(&mut self, file: FileID)

Create a new span with the given start and end offsets, and the given file.

pub fn with_file(self, file: FileID) -> FileSpan

Create a new span with the given start and end offsets, and the given file.

pub fn as_label<S>(&self, message: S) -> Label

where S: ToString,

Create a label from span

pub fn length(&self) -> usize

Get the length of this span (difference between the start of the span and the end of the span).

pub fn contains(&self, offset: usize) -> bool

Determine whether the span contains the given offset.

Trait Implementations

impl Clone for FileSpan

fn clone(&self) -> FileSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileSpan

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

Formats the value using the given formatter.

impl Default for FileSpan

fn default() -> FileSpan

Returns the “default value” for a type.

impl Display for FileSpan

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

Formats the value using the given formatter.

impl Hash for FileSpan

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FileSpan

fn eq(&self, other: &FileSpan) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
