Struct pyo3::ffi::PyASCIIObject

#[repr(C)]
pub struct PyASCIIObject {
    pub ob_base: PyObject,
    pub length: Py_ssize_t,
    pub hash: Py_hash_t,

Fields

ob_base: PyObject

length: Py_ssize_t

hash: Py_hash_t

state: u32

A bit field with various properties.

Rust doesn’t expose bitfields. So we have accessor functions for retrieving values.

unsigned int interned:2; // SSTATE_* constants. unsigned int kind:3; // PyUnicode_*_KIND constants. unsigned int compact:1; unsigned int ascii:1; unsigned int ready:1; unsigned int :24;

wstr: *mut wchar_t

Implementations

impl PyASCIIObject

Interacting with the bitfield is not actually well-defined, so we mark these APIs unsafe.

In addition, they are disabled on big-endian architectures to restrict this to most “common” platforms, which are at least tested on CI and appear to be sound.

pub unsafe fn interned(&self) -> c_uint

pub unsafe fn kind(&self) -> c_uint

pub unsafe fn compact(&self) -> c_uint

pub unsafe fn ascii(&self) -> c_uint

pub unsafe fn ready(&self) -> c_uint
