Trait OneShotWrite

pub trait OneShotWrite:
    Send
    + Sync
    + Unpin
    + 'static {
    // Required method
    fn write_once(
        &self,
        bs: Buffer,
    ) -> impl Future<Output = Result<Metadata>> + MaybeSend;
}

OneShotWrite is used to implement oio::Write based on one shot operation. By implementing OneShotWrite, services don’t need to care about the details.

For example, S3 PUT Object and fs write_all.

The layout after adopting OneShotWrite:

Required Methods

fn write_once( &self, bs: Buffer, ) -> impl Future<Output = Result<Metadata>> + MaybeSend

write_once write all data at once.

Implementations should make sure that the data is written correctly at once.

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.
