Trait Decode 

pub trait Decode: Sized {
    // Required method
    fn decode(value: &DbValue) -> Result<Self, Error>;
}

Available on crate feature pg only.

A type that can be decoded from the database.

Required Methods

fn decode(value: &DbValue) -> Result<Self, Error>

Decode a new value of this type using a DbValue.

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.
