}
Expand description

An encoder for values of a fixed schema

This allows us to amortize the cost of downcasting columns into concrete types.

Required Methods§

source

fn encode(&mut self, val: &T)

Encodes the given value into the Part being constructed.

source

fn finish(self) -> (usize, Vec<DynColumnMut>)

Consumes self returning the columns that were written to.
