Struct NpyView

pub struct NpyView<'a> { /* private fields */ }

Immutable view of memory-mapped .npy files within an .npz file.

Does not automatically verify CRC-32 checksum.

Implementations

impl NpyView<'_>

pub fn status(&self) -> ChecksumStatus

CRC-32 checksum status.

pub fn verify(&mut self) -> Result<u32, ViewNpzError>

Verifies and returns CRC-32 checksum by reading the whole array.

Changes checksum status to Outdated if invalid or to Correct if valid.

Errors

Fails with ZipError::Io if the checksum is invalid.

pub fn view<A, D>(&self) -> Result<ArrayView<'_, A, D>, ViewNpzError>

where A: ViewElement, D: Dimension,

Returns an immutable view of a memory-mapped .npy file.

Iterates over bool array to ensure 0x00/0x01 values.

Errors

Viewing an .npy file can fail with ViewNpyError.
