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<'a>(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.
