[−][src]Struct partial_io::PartialRead
A reader wrapper that breaks inner Read
instances up according to the
provided iterator.
Examples
use std::io::{Cursor, Read}; use partial_io::{PartialOp, PartialRead}; let reader = Cursor::new(vec![1, 2, 3, 4]); let iter = ::std::iter::repeat(PartialOp::Limited(1)); let mut partial_reader = PartialRead::new(reader, iter); let mut out = vec![0; 256]; let size = partial_reader.read(&mut out).unwrap(); assert_eq!(size, 1); assert_eq!(&out[..1], &[1]);
Implementations
impl<R> PartialRead<R> where
R: Read,
[src]
R: Read,
pub fn new<I>(inner: R, iter: I) -> Self where
I: IntoIterator<Item = PartialOp> + 'static,
I::IntoIter: Send,
[src]
I: IntoIterator<Item = PartialOp> + 'static,
I::IntoIter: Send,
Creates a new PartialRead
wrapper over the reader with the specified PartialOp
s.
pub fn set_ops<I>(&mut self, iter: I) -> &mut Self where
I: IntoIterator<Item = PartialOp> + 'static,
I::IntoIter: Send,
[src]
I: IntoIterator<Item = PartialOp> + 'static,
I::IntoIter: Send,
Sets the PartialOp
s for this reader.
pub fn get_ref(&self) -> &R
[src]
Acquires a reference to the underlying reader.
pub fn get_mut(&mut self) -> &mut R
[src]
Acquires a mutable reference to the underlying reader.
pub fn into_inner(self) -> R
[src]
Consumes this wrapper, returning the underlying reader.
