Struct IntoStringError

Source
pub struct IntoStringError { /* private fields */ }
🔬This is a nightly-only experimental API. (c_str_module #112134)
Expand description

An error indicating invalid UTF-8 when converting a CString into a String.

CString is just a wrapper over a buffer of bytes with a nul terminator; CString::into_string performs UTF-8 validation on those bytes and may return this error.

This struct is created by CString::into_string(). See its documentation for more.
