Struct Language

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

An opaque object that defines how to parse a particular language. The code for each Language is generated by the Tree-sitter CLI.

Implementations

impl Language

pub fn version(&self) -> usize

Get the ABI version number that indicates which version of the Tree-sitter CLI that was used to generate this Language.

pub fn node_kind_count(&self) -> usize

Get the number of distinct node types in this language.

pub fn node_kind_for_id(&self, id: u16) -> Option<&'static str>

Get the name of the node kind for the given numerical id.

pub fn id_for_node_kind(&self, kind: &str, named: bool) -> u16

Get the numeric id for the given node kind.

pub fn node_kind_is_named(&self, id: u16) -> bool

Check if the node type for the given numerical id is named (as opposed to an anonymous node type).

pub fn node_kind_is_visible(&self, id: u16) -> bool

pub fn field_count(&self) -> usize

Get the number of distinct field names in this language.

pub fn field_name_for_id(&self, field_id: u16) -> Option<&'static str>

Get the field names for the given numerical id.

pub fn field_id_for_name(&self, field_name: impl AsRef<[u8]>) -> Option<u16>

Get the numerical id for the given field name.

Trait Implementations

impl Clone for Language

fn clone(&self) -> Language

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Language

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

Formats the value using the given formatter.

impl Hash for Language

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 Language

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