Struct LanguageId 

pub struct LanguageId(pub Cow<'static, str>);

A language identifier string (e.g. "rust", "cpp", "python").

Built-in languages are represented as &'static str wrapped in Cow::Borrowed, so no allocation occurs for the common case. Future config-driven language IDs may use Cow::Owned.

Tuple Fields

0: Cow<'static, str>

Implementations

impl LanguageId

pub fn new(s: impl Into<Cow<'static, str>>) -> Self

Construct from any &'static str or String.

pub fn as_str(&self) -> &str

Borrow the inner string slice.

Trait Implementations

impl AsRef<str> for LanguageId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for LanguageId

fn clone(&self) -> LanguageId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LanguageId

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

Formats the value using the given formatter.

impl Display for LanguageId

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

Formats the value using the given formatter.

impl Hash for LanguageId

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 LanguageId

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