Structs§

BufferViewGuard 🔒: Drops an initialized view in place, including when the callback panics. The view’s storage is a MaybeUninit, so it will not be dropped a second time.
PyBuffer: A typed form of PyUntypedBuffer.
PyBufferRequest: Type-safe buffer request. The state parameter is intentionally hidden behind this wrapper so the internal encoding can evolve.
PyBufferView: A typed form of PyUntypedBufferView. Not constructible directly — use PyBufferView::with() or PyBufferView::with_flags().
PyUntypedBuffer: Allows access to the underlying buffer used by a python object such as bytes, bytearray or array.array.
PyUntypedBufferView: Stack-allocated untyped buffer view.
RawBuffer 🔒: Wrapper around ffi::Py_buffer to be !Unpin.
ReadOnlyCell: Like core::cell::Cell, but only provides read-only access to the data.

Enums§

ElementType: Represents the type of a Python buffer element.
PyBufferContiguity: Contiguity constraint encoded by a PyBufferRequest.

Traits§

Element: Trait implemented for possible element types of PyBuffer.

Functions§

check_buffer_compatibility 🔒: Check that a buffer is compatible with element type T.
debug_buffer 🔒
is_matching_endian 🔒 Little-endian
native_element_type_from_type_char 🔒
standard_element_type_from_type_char 🔒
