Struct TokenText

pub struct TokenText<T: TreeToken = SyntaxToken>(/* private fields */);

Helper for hashing tokens by their text.

Normally a token’s equality and hash implementation work by comparing the token’s element in the tree; thus, two tokens with the same text but different positions in the tree will compare and hash differently.

With this hash implementation, two tokens compare and hash identically if their text is identical.

Implementations

impl TokenText

pub fn text(&self) -> &str

Gets the text of the underlying token.

pub fn span(&self) -> Span

Gets the span of the underlying token.

Trait Implementations

impl<T: TreeToken> Borrow<str> for TokenText<T>

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl<T: Clone + TreeToken> Clone for TokenText<T>

fn clone(&self) -> TokenText<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + TreeToken> Debug for TokenText<T>

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

Formats the value using the given formatter.

impl<T: TreeToken> Hash for TokenText<T>

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<T: TreeToken> PartialEq for TokenText<T>

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