Function glib::convert

pub fn convert(
    str_: &[u8],
    to_codeset: impl IntoGStr,
    from_codeset: impl IntoGStr
) -> Result<(Slice<u8>, usize), CvtError>

Converts a string from one character set to another.

Note that you should use g_iconv() for streaming conversions. Despite the fact that @bytes_read can return information about partial characters, the g_convert_… functions are not generally suitable for streaming. If the underlying converter maintains internal state, then this won’t be preserved across successive calls to g_convert(), g_convert_with_iconv() or g_convert_with_fallback(). (An example of this is the GNU C converter for CP1255 which does not emit a base character until it knows that the next character is not a mark that could combine with the base character.)

Using extensions such as “//TRANSLIT” may not work (or may not work well) on many platforms. Consider using g_str_to_ascii() instead.

str

            the string to convert.

to_codeset

name of character set into which to convert @str

from_codeset

character set of @str.

Returns

     If the conversion was successful, a newly allocated buffer
     containing the converted string, which must be freed with g_free().
     Otherwise [`None`] and @error will be set.

bytes_read

location to store the number of bytes in the input string that were successfully converted, or None. Even if the conversion was successful, this may be less than @len if there were partial characters at the end of the input. If the error ConvertError::IllegalSequence occurs, the value stored will be the byte offset after the last valid input sequence.
