Expand description

Progress of writing a Fragment.

When start writing a Fragment, WriteProgress::begin() will be called before writing any data.

When stop writing a Fragment, WriteProgress::complete() will be called after.

This might be called concurrently when writing multiple Fragments. Therefore, the methods require non-exclusive access to self.

This is an experimental API and may change in the future.

Required Methods§

Source

fn begin<'life0, 'life1, 'async_trait>( &'life0 self, fragment: &'life1 Fragment, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Indicate the beginning of writing a Fragment, with the in-flight multipart ID.

Source

fn complete<'life0, 'life1, 'async_trait>( &'life0 self, fragment: &'life1 Fragment, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Complete writing a Fragment.

Dyn Compatibility§

This trait is dyn compatible.

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