pub struct MemmapArrayMut<T: Element> { /* private fields */ }Expand description
A read-write memory-mapped array backed by a .npy file.
Modifications to the array data are written back to the underlying file.
Implementations§
Source§impl<T: Element> MemmapArrayMut<T>
impl<T: Element> MemmapArrayMut<T>
Sourcepub fn as_slice_mut(&mut self) -> &mut [T]
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).
Sourcepub fn to_array(&self) -> FerrayResult<Array<T, IxDyn>>
pub fn to_array(&self) -> FerrayResult<Array<T, IxDyn>>
Copy the memory-mapped data into an owned Array.
Sourcepub fn flush(&self) -> FerrayResult<()>
pub fn flush(&self) -> FerrayResult<()>
Flush changes to disk (only meaningful for ReadWrite mode).
