Lance Write Extension.

Required Methods§

Source

fn write_protobuf<'life0, 'life1, 'async_trait>( &'life0 mut self, msg: &'life1 (impl 'async_trait + Message), ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write a Protobuf message to the Writer, and returns the file position where the protobuf is written.

Source

fn write_magics<'life0, 'life1, 'async_trait>( &'life0 mut self, pos: usize, major_version: i16, minor_version: i16, magic: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Write magics to the tail of a file before closing the file.

Provided Methods§

Source

fn write_struct<'b, 'life0, 'async_trait, M, T>( &'life0 mut self, obj: &'b T, ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>
where M: 'async_trait + Message + From<&'b T>, T: 'async_trait + ProtoStruct<Proto = M> + Send + Sync + 'b, Self: Send + 'async_trait, 'b: 'async_trait, 'life0: 'async_trait,

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.
