Trait ValueStrategy 

pub trait ValueStrategy<T>:
    Send
    + Sync
    + Clone {
    const IS_NATIVE_LAYOUT: bool = false;

    // Required methods
    fn read(bytes: &[u8]) -> Result<T>;
    fn write_to_vec(value: &T, buf: &mut Vec<u8>);
    fn write_to_slice(value: &T, dst: &mut [u8]);
}

Value serialization strategy shared by all vec types (raw and compressed).

Handles reading/writing individual values to/from bytes.

Provided Associated Constants

const IS_NATIVE_LAYOUT: bool = false

Whether T has native memory layout (can be memcpy’d to/from bytes).

Required Methods

fn read(bytes: &[u8]) -> Result<T>

Deserializes a value from its byte representation.

fn write_to_vec(value: &T, buf: &mut Vec<u8>)

Serializes a value by appending its byte representation to the buffer.

fn write_to_slice(value: &T, dst: &mut [u8])

Serializes a value directly into a fixed-size slice.

Dyn Compatibility

This trait is not dyn compatible.

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