Struct handy_io::pattern::read::Until

pub struct Until<F, T> { /* fields omitted */ }

A pattern which continues reading until the predicate F is satisfied.

Methods

impl<F, T> Until<F, T>

fn unwrap(self) -> (F, usize, usize)

fn min_buffer_size(self, size: usize) -> Self

Sets minimum (i.e., initial) buffer size.

fn max_buffer_size(self, size: usize) -> Self

Sets maiximum buffer size allowed to read.

Trait Implementations

impl<R: Read, F, T> ReadFrom<R> for Until<F, T> where
    F: Fn(&[u8], bool) -> Result<Option<T>>, 

type Future = ReadUntil<R, F, T>

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<F: Debug, T: Debug> Debug for Until<F, T>

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

Formats the value using the given formatter.

impl<F, T> Pattern for Until<F, T>

type Value = (Vec<u8>, 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.
