Trait Decoder 

pub trait Decoder: Sized {
    // Required method
    fn decode(reader: &mut Bytes) -> Result<Self>;
}

Trait for types that can be decoded from the senax binary format.

Implement this trait for your type to enable deserialization. Most users should use #[derive(Decode)] instead of manual implementation.

Errors

Returns EncoderError if the value cannot be decoded or the data is invalid.

Required Methods

fn decode(reader: &mut Bytes) -> Result<Self>

Decode the value from the given buffer with schema evolution support.

This method expects field IDs and type tags for forward/backward compatibility. Use this when you need schema evolution support.

Arguments

• reader - The buffer to read the encoded bytes from.

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.

Implementations on Foreign Types

impl Decoder for bool

Errors

Returns an error if the tag is not TAG_ZERO or TAG_ONE.

fn decode(reader: &mut Bytes) -> Result<Self>

impl Decoder for char
