Trait Implementations

impl<F: Clone> Clone for Fail<F>

fn clone(&self) -> Fail<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug> Debug for Fail<F>

where Self: Sized, B: Parser<Input, Error = Self::Error>,

fn and_skip<B>(self, b: B) -> P<AndSkip<Self, B>>

impl<F: PartialEq> PartialEq for Fail<F>

fn eq(&self, other: &Fail<F>) -> 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.
