Struct ClonableSeek 

pub struct ClonableSeek<'reader, R: Read<Error: Copy> + Seek> { /* private fields */ }

A wrapper which allows cheaply and safely cloning implementors of Seek.

This defers ownership of the reader for solely ownership of a reference to it. Each instance individually tracks their position within the reader, resetting the seek head on each invocation (as required for each instance to maintain a consistent view).

Trait Implementations

impl<'reader, R: Read<Error: Copy> + Seek> Clone for ClonableSeek<'reader, R>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'reader, R: Read<Error: Copy> + Seek> ErrorType for ClonableSeek<'reader, R>

type Error = <R as ErrorType>::Error

Error type of all the IO operations on this type.

impl<'reader, R: Read<Error: Copy> + Seek> Read for ClonableSeek<'reader, R>

fn read(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl<'reader, R: Read<Error: Copy> + Seek> Seek for ClonableSeek<'reader, R>

fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Error>

Seek to an offset, in bytes, in a stream. A seek beyond the end of a stream is allowed, but behavior is defined by the implementation.

fn rewind(&mut self) -> Result<(), Self::Error>

Rewind to the beginning of a stream.

fn stream_position(&mut self) -> Result<u64, Self::Error>

Returns the current seek position from the start of the stream.

fn seek_relative(&mut self, offset: i64) -> Result<(), Self::Error>

Seeks relative to the current position.

impl<'reader, R: Read<Error: Copy> + Seek> TryFrom<&'reader RefCell<R>> for ClonableSeek<'reader, R>

type Error = <R as ErrorType>::Error

The type returned in the event of a conversion error.

fn try_from(reader: &'reader RefCell<R>) -> Result<Self, R::Error>

Performs the conversion.
