Struct MemmapArrayMut 

pub struct MemmapArrayMut<T: Element> { /* private fields */ }

A read-write memory-mapped array backed by a .npy file.

Modifications to the array data are written back to the underlying file.

Implementations

impl<T: Element> MemmapArrayMut<T>

pub fn shape(&self) -> &[usize]

Return the shape of the mapped array.

pub fn as_slice(&self) -> &[T]

Return the mapped data as a slice.

pub fn as_slice_mut(&mut self) -> &mut [T]

Return the mapped data as a mutable slice.

Modifications will be persisted to the file (for ReadWrite mode) or kept in memory only (for CopyOnWrite mode).

pub fn to_array(&self) -> FerrayResult<Array<T, IxDyn>>

Copy the memory-mapped data into an owned Array.

pub fn view(&self) -> ArrayView<'_, T, IxDyn>

Borrow the memory-mapped data as an immutable ArrayView<T, IxDyn>. See MemmapArray::view for the rationale (#496).

pub fn flush(&self) -> FerrayResult<()>

Flush changes to disk (only meaningful for ReadWrite mode).
