Enum Step 

pub enum Step<T> {
    Start(T),
    Error(Error),
    End,
    Bump(Fingerprint),
    Delete,
}

Variants

Start(T)

Error(Error)

End

Bump(Fingerprint)

Delete

Delete (skip) the current token. The token still appears in the CST wrapped in an Error node, but no grammar rule consumes it.

Implementations

impl<T: TokenTrait> Step<T>

pub fn start(kind: T) -> Self

pub fn error(error: Error) -> Self

pub fn end() -> Self

Trait Implementations

impl<T: Clone> Clone for Step<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Step<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Step<T>

fn eq(&self, other: &Step<T>) -> 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.
