Struct opendal::raw::oio::Cursor

pub struct Cursor { /* private fields */ }

Cursor is the cursor for [Bytes] that implements oio::Read

Implementations

impl Cursor

pub fn is_empty(&self) -> bool

Returns true if the remaining slice is empty.

pub fn remaining_slice(&self) -> &[u8]

Returns the remaining slice.

Trait Implementations

impl BlockingRead for Cursor

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

Read synchronously.

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

Seek synchronously.

fn next(&mut self) -> Option<Result<Bytes>>

Iterating [Bytes] from underlying reader.

impl From<Vec<u8, Global>> for Cursor

fn from(v: Vec<u8>) -> Self

Converts to this type from the input type.

impl Read for Cursor

fn poll_read(
    &mut self,
    _: &mut Context<'_>,
    buf: &mut [u8]
) -> Poll<Result<usize>>

Read bytes asynchronously.

fn poll_seek(&mut self, _: &mut Context<'_>, pos: SeekFrom) -> Poll<Result<u64>>

Seek asynchronously.

fn poll_next(&mut self, _: &mut Context<'_>) -> Poll<Option<Result<Bytes>>>
