    fn is_size_suitable(usize) -> bool;
}

Trait for types of data that can be put inside buffers.

Associated Types

type Owned

A type that holds a sized version of the content.

Required Methods

fn read<F, E>(size: usize, F) -> Result<Self::Owned, E> where
    F: FnOnce(&mut Self) -> Result<(), E>, 

Prepares an output buffer, then turns this buffer into an Owned.

fn get_elements_size() -> usize

Returns the size of each element.

fn to_void_ptr(&self) -> *const ()

Produces a pointer to the data.

fn ref_from_ptr(ptr: *mut (), size: usize) -> Option<*mut Self>

Builds a pointer to this type from a raw pointer.

fn is_size_suitable(usize) -> bool

Returns true if the size is suitable to store a type like this.
