Struct glib::IConv

source ·
pub struct IConv(_);


Converts a string from one character set to another.

Note that you should use [iconv()][crate::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 convert(), convert() or 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.)

Characters which are valid in the input character set, but which have no representation in the output character set will result in a ConvertError::IllegalSequence error. This is in contrast to the iconv() specification, which leaves this behaviour implementation defined. Note that this is the same error code as is returned for an invalid byte sequence in the input character set. To get defined behaviour for conversion of unrepresentable characters, use convert_with_fallback().

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.


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.
