Trait PyStringMethods 

pub trait PyStringMethods<'py>: Sealed {
    // Required methods
    fn to_cow(&self) -> PyResult<Cow<'_, str>>;
    fn to_string_lossy(&self) -> Cow<'_, str>;
    fn encode_utf8(&self) -> PyResult<Bound<'py, PyBytes>>;
}

Implementation of functionality for PyString.

These methods are defined for the Bound<'py, PyString> smart pointer, so to use method call syntax these methods are separated into a trait, because stable Rust does not yet support arbitrary_self_types.

Required Methods

fn to_cow(&self) -> PyResult<Cow<'_, str>>

Converts the PyString into a Rust string, avoiding copying when possible.

Returns a UnicodeEncodeError if the input is not valid unicode (containing unpaired surrogates).

fn to_string_lossy(&self) -> Cow<'_, str>

Converts the PyString into a Rust string.

Unpaired surrogates invalid UTF-8 sequences are replaced with U+FFFD REPLACEMENT CHARACTER.

fn encode_utf8(&self) -> PyResult<Bound<'py, PyBytes>>

Encodes this string as a Python bytes object, using UTF-8 encoding.
