Trait WriteBytes

pub trait WriteBytes: Sized {
    // Required methods
    fn block_size(&self) -> u64;
    fn write_bytes(
        &mut self,
        buf: &[u8],
    ) -> impl Future<Output = Result<(), Error>> + Send;
    fn complete(&mut self) -> impl Future<Output = Result<(), Error>> + Send;
    fn skip(
        &mut self,
        amount: u64,
    ) -> impl Future<Output = Result<(), Error>> + Send;
}

This trait is an asynchronous streaming writer.

Required Methods

fn block_size(&self) -> u64

fn write_bytes( &mut self, buf: &[u8], ) -> impl Future<Output = Result<(), Error>> + Send

Buffers writes to be written to the underlying handle. This may flush bytes immediately or when buffers are full.

fn complete(&mut self) -> impl Future<Output = Result<(), Error>> + Send

Called to flush to the handle. Named to avoid conflict with the flush method above.

fn skip( &mut self, amount: u64, ) -> impl Future<Output = Result<(), Error>> + Send

Moves the offset forward by amount, which will result in zeroes in the output stream, even if no other data is appended to it.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
