Trait Implementations

impl<T: Type> AsMut<[T]> for Mmap<T>

fn as_mut(&mut self) -> &mut [T]

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T: Type> AsRef<[T]> for Mmap<T>

fn as_ref(&self) -> &[T]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Type> Drop for Mmap<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T: Type> ImageData<T> for Mmap<T>

fn flush(&self) -> Result<(), Error>
