Trait Implementations

impl<R: Read> ReadFrom<R> for I32

type Future = <Map<Buf<[u8; 4]>, fn(_: Buf<[u8; 4]>::Value) -> Self::Value> as ReadFrom<R>>::Future

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>

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

fn sync_read_from(self, reader: R) -> Result<Self::Value>

Scynchronously reading a value of the pattern from reader.

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

Returns the boxed version of this pattern.

impl Debug for I32

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

Formats the value using the given formatter.

impl Clone for I32

fn clone(&self) -> I32

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Pattern for I32

type Value = i32

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.

impl Endian for I32

fn le(self) -> LE<Self>

Indicates that "This is a little endian pattern".

fn be(self) -> BE<Self>

Indicates that "This is a big endian pattern".
