Implementations§

source§

impl<'a> PyStringData<'a>

source

pub fn to_string(self, py: Python<'_>) -> PyResult<Cow<'a, str>>

Convert the Python string data to a Rust string.

For UTF-8 and ASCII-only latin-1, returns a borrow into the original string data. For Latin-1, UTF-16 and UTF-32, returns an owned string.

Fails with UnicodeDecodeError if the string data isn’t valid in its encoding.

source

pub fn to_string_lossy(self) -> Cow<'a, str>

Convert the Python string data to a Rust string.

Returns a borrow into the original string data if possible.

Data that isn’t valid in its encoding will be replaced with U+FFFD REPLACEMENT CHARACTER.
