Trait Decode 

pub trait Decode: Encode + Sized {
    type Ref<'a>;

    // Required methods
    fn decode(bytes: &[u8]) -> Result<Self>;
    fn view(bytes: &[u8]) -> Result<Self::Ref<'_>>;
}

A type that can be read back out of a record.

Decode::Ref is the borrowed view: the form that reads out of the arena without copying, which is Y29 and where G6’s point read budget lives. The owned form is one call away for the code that does not care.

Required Associated Types

type Ref<'a>

The borrowed view of this type.

Required Methods

fn decode(bytes: &[u8]) -> Result<Self>

Read an owned value.

Errors

Code::Corrupt when the bytes are not this type, which means the collection holds something the shape said it did not.

fn view(bytes: &[u8]) -> Result<Self::Ref<'_>>

Read a borrowed view, which copies nothing.

Errors

The same as Decode::decode.

Dyn Compatibility

This trait is not dyn compatible.

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