Trait ic_stable_structures::storable::Storable

pub trait Storable {
    const BOUND: Bound;

    // Required methods
    fn to_bytes(&self) -> Cow<'_, [u8]>;
    fn from_bytes(bytes: Cow<'_, [u8]>) -> Self;

    // Provided method
    fn to_bytes_checked(&self) -> Cow<'_, [u8]> { ... }
}

A trait with convenience methods for storing an element into a stable structure.

Required Associated Constants

const BOUND: Bound

The size bounds of the type.

Required Methods

fn to_bytes(&self) -> Cow<'_, [u8]>

Converts an element into bytes.

NOTE: Cow is used here to avoid unnecessary cloning.

fn from_bytes(bytes: Cow<'_, [u8]>) -> Self

Converts bytes into an element.

Provided Methods

fn to_bytes_checked(&self) -> Cow<'_, [u8]>

Like to_bytes, but includes additional checks to ensure the element’s serialized bytes are within the element’s bounds.

Object Safety

This trait is not object safe.
