Trait StateMut 

pub trait StateMut<T> {
    // Required methods
    fn state(&self) -> Result<T, InstructionError>;
    fn set_state(&mut self, state: &T) -> Result<(), InstructionError>;
}

Convenience trait to covert bincode errors to instruction errors.

Required Methods

fn state(&self) -> Result<T, InstructionError>

fn set_state(&mut self, state: &T) -> Result<(), InstructionError>

Dyn Compatibility

This trait is dyn compatible.

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