Trait for writing file.

TODO

It’s possible for us to remove the async_trait, but we need to figure out how to handle the object safety.

Required Methods

fn write<'life0, 'async_trait>( &'life0 mut self, bs: Bytes, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Write bytes to file.

TODO: we can support writing non-contiguous bytes in the future.

fn close<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Close file.

Calling close on closed file will generate an error.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
