Trait ValueEncoder

Source

pub trait ValueEncoder<Input: ?Sized> {
    type Output;
    type Error;

    // Required method
    fn encode(&mut self, input: &Input) -> Result<Self::Output, Self::Error>;
}

Expand description

Encodes a borrowed input value into an owned representation.

This trait is a convenience-layer API. Use crate::Codec for low-level single-value buffer encoding and crate::Transcoder for batch conversion over caller-provided buffers.

§Examples

use qubit_codec::ValueEncoder;

struct TextEncoder;
impl ValueEncoder<str> for TextEncoder {
    type Output = Vec<u8>;
    type Error = core::convert::Infallible;

    fn encode(&mut self, input: &str) -> Result<Self::Output, Self::Error> {
        Ok(input.as_bytes().to_vec())
    }
}

let mut encoder = TextEncoder;
assert_eq!(encoder.encode("hello").unwrap(), b"hello");
