Struct pyo3::types::PyUnicode

source ·
pub struct PyUnicode(/* private fields */);
Expand description

Represents a Python string (a Unicode string object).

This type is immutable.

Implementations§

source§

impl PyString

source

pub fn new_bound<'py>(py: Python<'py>, s: &str) -> Bound<'py, PyString>

Creates a new Python string object.

Panics if out of memory.

source

pub fn intern_bound<'py>(py: Python<'py>, s: &str) -> Bound<'py, PyString>

Intern the given string

This will return a reference to the same Python string object if called repeatedly with the same string.

Note that while this is more memory efficient than PyString::new_bound, it unconditionally allocates a temporary Python string object and is thereby slower than PyString::new_bound.

Panics if out of memory.

source

pub fn from_object_bound<'py>( src: &Bound<'py, PyAny>, encoding: &str, errors: &str ) -> PyResult<Bound<'py, PyString>>

Attempts to create a Python string from a Python bytes-like object.
