Trait StreamFormatEncode 

pub trait StreamFormatEncode<T>: StreamFormat {
    type Encoder: ItemEncoder<T>;

    // Required method
    fn encoder(&self) -> Self::Encoder;
}

Encodes items of type T into bytes.

Required Associated Types

type Encoder: ItemEncoder<T>

The per-stream encoder. A fresh one is built for every body, because framing state (item index, Arrow’s dictionary tracker, CSV’s header flag) is per-stream.

Required Methods

fn encoder(&self) -> Self::Encoder

Build an encoder for one body.

Dyn Compatibility

This trait is dyn compatible.

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