Trait StorageWithCapacity 

pub unsafe trait StorageWithCapacity: Storage + Sized {
    // Required method
    fn with_capacity(capacity: usize) -> Self;
}

A storage that can be initially created with a given capacity

Safety

The storage must have a capacity of at least capacity after StorageWithCapacity::with_capacity is called.

Required Methods

fn with_capacity(capacity: usize) -> Self

Creates a new storage with at least the given storage capacity

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
