Struct handy_io::io::BoxWriteTo

pub struct BoxWriteTo<W, T>(_);

Boxed object which implements WriteTo trait.

This object can be created with the WriteTo::boxed method.

Trait Implementations

impl<W, T> Pattern for BoxWriteTo<W, T>

type Value = T

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<W: Write, T> WriteTo<W> for BoxWriteTo<W, T>

type Future = IoFuture<W, T>

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.
