Struct Version 

pub struct Version(/* private fields */);

A node in the syntax tree for $ast

Implementations

impl Version

pub fn text_range(&self) -> TextRange

Byte range covered by this node in the source buffer.

Useful for editors that need to map a logical concept (an option, a URL, a matching pattern) back to the exact span it occupies — e.g. to filter LSP diagnostics by which part of a watch entry was edited.

pub fn line(&self) -> usize

Get the line number (0-indexed) where this node starts.

pub fn column(&self) -> usize

Get the column number (0-indexed, in bytes) where this node starts.

pub fn line_col(&self) -> (usize, usize)

Get both line and column (0-indexed) where this node starts. Returns (line, column) where column is measured in bytes from the start of the line.

impl Version

pub fn version(&self) -> u32

Returns the version of the watch file.

Trait Implementations

impl Clone for Version

fn clone(&self) -> Version

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Version

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

Formats the value using the given formatter.

impl Display for Version

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

Formats the value using the given formatter.

impl Hash for Version

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

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 Version

fn eq(&self, other: &Version) -> 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.
