Trait Implementations

impl<R: Read, B: AsMut<[u8]>> ReadFrom<R> for Buf<B>

type Future = Map<ReadBuf<R, Self>, fn(_: (R, Buf<B>)) -> (R, B)>

The future to read a value of the pattern from R.

fn lossless_read_from(self, reader: R) -> Self::Future

Creates a future instance to read a value of the pattern from reader.

fn read_from(self, reader: R) -> LossyReadFrom<R, Self::Future>

Returns the boxed version of this pattern.

impl<W: Write, B: AsRef<[u8]>> WriteTo<W> for Buf<B>

type Future = WriteBuf<W, B>

The future to write a value of the pattern to W.

fn lossless_write_to(self, writer: W) -> Self::Future

Creates a future instance to write a value of the pattern to writer.

fn write_to(self, writer: W) -> LossyWriteTo<W, Self::Future>

Creates a future instance to write a value of the pattern to writer.

fn sync_write_to(self, writer: W) -> Result<Self::Value>

Scynchronously writing a value of the pattern to writer.

fn boxed(self) -> BoxWriteTo<W, Self::Value> where
    Self: Send + 'static,
    Self::Future: Send + 'static, 

Returns the boxed version of this pattern.

impl<B: Debug> Debug for Buf<B>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<B: Clone> Clone for Buf<B>

fn clone(&self) -> Buf<B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<B> AllowPartial for Buf<B>

fn allow_partial(self) -> PartialBuf<Self>

Indicates that this pattern is partially evaluable.

impl<B: AsRef<[u8]>> AsRef<[u8]> for Buf<B>

fn as_ref(&self) -> &[u8]

Performs the conversion.

impl<B: AsMut<[u8]>> AsMut<[u8]> for Buf<B>

fn as_mut(&mut self) -> &mut [u8]

Performs the conversion.

impl<B> Pattern for Buf<B>

type Value = B

The value type associated to the pattern.

fn then<F, P>(self, f: F) -> Then<Self, F> where
    F: FnOnce(Result<Self::Value>) -> P, 

Takes a closure which maps a Result<Self::Value> to a pattern, and creates a pattern which calls that closure on the evaluation result of self.

fn and_then<F, P>(self, f: F) -> AndThen<Self, F> where
    F: FnOnce(Self::Value) -> P, 

Takes a closure which maps a value to a pattern, and creates a pattern which calls that closure if the evaluation of self was succeeded.

fn or_else<F, P>(self, f: F) -> OrElse<Self, F> where
    F: FnOnce(Error) -> P, 

Takes a closure which maps an error to a pattern, and creates a pattern which calls that closure if the evaluation of self failed.

fn map<F, T>(self, f: F) -> Map<Self, F> where
    F: FnOnce(Self::Value) -> T, 

Takes a closure which maps a value to another value, and creates a pattern which calls that closure on the evaluated value of self.

fn chain<P>(self, other: P) -> Chain<Self, P> where
    P: Pattern, 

Takes two patterns and creates a new pattern over both in sequence.

fn repeat(self) -> Repeat<Self> where
    Self: Clone, 

Creates Repeat pattern to represent an infinite stream of this pattern.
