Trait Decode

pub trait Decode:
    Sized
    + Send
    + Sync
    + Debug {
    // Required method
    fn decode(value: &[u8]) -> Result<Self, DatabaseError>;

    // Provided method
    fn decode_owned(value: Vec<u8>) -> Result<Self, DatabaseError> { ... }
}

Trait that will transform the data to be read from the DB.

Required Methods

fn decode(value: &[u8]) -> Result<Self, DatabaseError>

Decodes data coming from the database.

Provided Methods

fn decode_owned(value: Vec<u8>) -> Result<Self, DatabaseError>

Decodes owned data coming from the database.

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.
