Trait WordValue 

pub trait WordValue: Sized {
    // Required methods
    fn try_into_word(self) -> Result<Word, &'static str>;
    fn try_from_word(word: Word) -> Result<Self, &'static str>;
}

A type that can be stored in (or loaded from) account storage.

Storage slots and map items store a single Word. Implementations must define a reversible conversion between the Rust type and a Word.

Required Methods

fn try_into_word(self) -> Result<Word, &'static str>

Converts the value into the single storage word used by the host.

fn try_from_word(word: Word) -> Result<Self, &'static str>

Reconstructs the value from the single storage word returned by the host.

Dyn Compatibility

This trait is not dyn compatible.

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