Struct vortex_io::VortexBufReader

pub struct VortexBufReader<R> { /* private fields */ }

A stateful asynchronous reader that wraps an internal stateless reader.

Read operations will advance the cursor.

Implementations

impl<R> VortexBufReader<R>

pub fn new(inner: R) -> Self

Create a new buffered reader wrapping a stateless reader, with reads beginning at offset 0.

pub fn set_position(&mut self, pos: u64)

Set the position of the next read_bytes call directly.

Note: this method will not fail if the position is past the end of the valid range, the failure will occur at read time and result in an UnexpectedEof error.

impl<R: VortexReadAt> VortexBufReader<R>

pub async fn read_bytes(&mut self, len: u64) -> Result<Buffer>

Perform an exactly-sized read at the current cursor position, advancing the cursor and returning the bytes.

If there are not enough bytes available to fulfill the request, an UnexpectedEof error is returned.

Trait Implementations

impl<R: Clone> Clone for VortexBufReader<R>

fn clone(&self) -> VortexBufReader<R>

Returns a copy of the value.

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

Performs copy-assignment from source.
