Struct cpython::PyBytes
[−]
[src]
pub struct PyBytes(_);
Represents a Python byte string.
Corresponds to str
in Python 2, and bytes
in Python 3.
Methods
impl PyBytes
[src]
fn new(py: Python, s: &[u8]) -> PyBytes
Creates a new Python byte string object.
The byte string is initialized by copying the data from the &[u8]
.
Panics if out of memory.
fn data(&self, _py: Python) -> &[u8]
Gets the Python string data as byte slice.
Trait Implementations
impl ToPyObject for PyBytes
[src]
Identity conversion: allows using existing PyObject
instances where
T: ToPyObject
is expected.
type ObjectType = PyBytes
fn to_py_object(&self, py: Python) -> PyBytes
Converts self into a Python object.
fn into_py_object(self, _py: Python) -> PyBytes
Converts self into a Python object. Read more
fn with_borrowed_ptr<F, R>(&self, _py: Python, f: F) -> R where
F: FnOnce(*mut PyObject) -> R,
F: FnOnce(*mut PyObject) -> R,
Converts self into a Python object and calls the specified closure on the native FFI pointer underlying the Python object. Read more
impl<'source> FromPyObject<'source> for PyBytes
[src]
fn extract(py: Python, obj: &'source PyObject) -> PyResult<PyBytes>
Extracts Self
from the source PyObject
.
impl<'source> FromPyObject<'source> for &'source PyBytes
[src]
fn extract(py: Python, obj: &'source PyObject) -> PyResult<&'source PyBytes>
Extracts Self
from the source PyObject
.
impl PythonObject for PyBytes
[src]
fn as_object(&self) -> &PyObject
Casts the Python object to PyObject.
fn into_object(self) -> PyObject
Casts the Python object to PyObject.
unsafe fn unchecked_downcast_from(obj: PyObject) -> Self
Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.
unsafe fn unchecked_downcast_borrow_from<'a>(obj: &'a PyObject) -> &'a Self
Unchecked downcast from PyObject to Self. Undefined behavior if the input object does not have the expected type.
impl PythonObjectWithCheckedDowncast for PyBytes
[src]
fn downcast_from<'p>(
py: Python<'p>,
obj: PyObject
) -> Result<PyBytes, PythonObjectDowncastError<'p>>
py: Python<'p>,
obj: PyObject
) -> Result<PyBytes, PythonObjectDowncastError<'p>>
Cast from PyObject to a concrete Python object type.
fn downcast_borrow_from<'a, 'p>(
py: Python<'p>,
obj: &'a PyObject
) -> Result<&'a PyBytes, PythonObjectDowncastError<'p>>
py: Python<'p>,
obj: &'a PyObject
) -> Result<&'a PyBytes, PythonObjectDowncastError<'p>>
Cast from PyObject to a concrete Python object type.
impl PythonObjectWithTypeObject for PyBytes
[src]
fn type_object(py: Python) -> PyType
Retrieves the type object for this Python object type.
