Struct DynZeroCopyInputStream

pub struct DynZeroCopyInputStream<'a> { /* private fields */ }

An arbitrary stream that implements ZeroCopyInputStream.

This is like Box<dyn ZeroCopyInputStream> but it avoids additional virtual method calls on the Rust side of the FFI boundary.

Trait Implementations

impl<'a> Drop for DynZeroCopyInputStream<'a>

fn drop(&mut self)

Executes the destructor for this type.

impl ZeroCopyInputStream for DynZeroCopyInputStream<'_>

fn next(self: Pin<&mut Self>) -> Result<&[u8], OperationFailedError>

Obtains a chunk of data from the stream.

fn back_up(self: Pin<&mut Self>, count: usize)

Backs up a number of bytes, so that the next call to next returns data again that was already returned by the last call to next.

fn skip(self: Pin<&mut Self>, count: usize) -> Result<(), OperationFailedError>

Skips count bytes.

fn byte_count(&self) -> i64

Returns the total number of bytes read since this stream was created.
