Trait MaxSize 

pub trait MaxSize {
    const POSTCARD_MAX_SIZE: usize;
}

This trait is used to enforce the maximum size required to store the serialization of a given type.

Required Associated Constants

const POSTCARD_MAX_SIZE: usize

The maximum possible size that the serialization of this type can have, in bytes.

Dyn Compatibility

This trait is not dyn compatible.

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