    -- binary data in various ways. The conversion can be
    -- stateful and may fail at any place.
    --
    -- Some example conversions are: character set conversion,
    -- compression, decompression and regular expression
    -- replace.

    --
    -- If any data was either produced or consumed, and then an error happens, then
    -- only the successful conversion is reported and the error is returned on the
    -- next call.
    --
    -- A full conversion loop involves calling this method repeatedly, each time
    -- giving it new input and space output space. When there is no more input
    -- data after the data in /@inbuf@/, the flag 'GI.Gio.Flags.ConverterFlagsInputAtEnd' must be set.
    -- The loop will be (unless some error happens) returning 'GI.Gio.Enums.ConverterResultConverted'
    -- each time until all data is consumed and all output is produced, then
    -- 'GI.Gio.Enums.ConverterResultFinished' is returned instead. Note, that 'GI.Gio.Enums.ConverterResultFinished'
    -- may be returned even if 'GI.Gio.Flags.ConverterFlagsInputAtEnd' is not set, for instance
    -- in a decompression converter where the end of data is detectable from the
    -- data (and there might even be other data after the end of the compressed data).
    --
    -- When some data has successfully been converted /@bytesRead@/ and is set to
    -- the number of bytes read from /@inbuf@/, and /@bytesWritten@/ is set to indicate
    -- how many bytes was written to /@outbuf@/. If there are more data to output
    -- or consume (i.e. unless the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' is specified) then
    -- 'GI.Gio.Enums.ConverterResultConverted' is returned, and if no more data is to be output
    -- then 'GI.Gio.Enums.ConverterResultFinished' is returned.
    --
    -- On error 'GI.Gio.Enums.ConverterResultError' is returned and /@error@/ is set accordingly.
    -- Some errors need special handling:
    --
    -- 'GI.Gio.Enums.IOErrorEnumNoSpace' is returned if there is not enough space
    -- to write the resulting converted data, the application should
    -- call the function again with a larger /@outbuf@/ to continue.
    --
    -- 'GI.Gio.Enums.IOErrorEnumPartialInput' is returned if there is not enough
    -- input to fully determine what the conversion should produce,
    -- and the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' flag is not set. This happens for
    -- example with an incomplete multibyte sequence when converting text,
    -- or when a regexp matches up to the end of the input (and may match
    -- further input). It may also happen when /@inbufSize@/ is zero and
    -- there is no more data to produce.
    --
    -- When this happens the application should read more input and then
    -- call the function again. If further input shows that there is no
    -- more data call the function again with the same data but with
    -- the 'GI.Gio.Flags.ConverterFlagsInputAtEnd' flag set. This may cause the conversion
    -- to finish as e.g. in the regexp match case (or, to fail again with
    -- 'GI.Gio.Enums.IOErrorEnumPartialInput' in e.g. a charset conversion where the
    -- input is actually partial).
    --
    -- After 'GI.Gio.Interfaces.Converter.converterConvert' has returned 'GI.Gio.Enums.ConverterResultFinished' the
    -- converter object is in an invalid state where its not allowed
    -- to call 'GI.Gio.Interfaces.Converter.converterConvert' anymore. At this time you can only
    -- free the object or call 'GI.Gio.Interfaces.Converter.converterReset' to reset it to the
    -- initial state.
    --
    -- If the flag 'GI.Gio.Flags.ConverterFlagsFlush' is set then conversion is modified
    -- to try to write out all internal state to the output. The application
    -- has to call the function multiple times with the flag set, and when
    -- the available input has been consumed and all internal state has
    -- been produced then 'GI.Gio.Enums.ConverterResultFlushed' (or 'GI.Gio.Enums.ConverterResultFinished' if
    -- really at the end) is returned instead of 'GI.Gio.Enums.ConverterResultConverted'.
    -- This is somewhat similar to what happens at the end of the input stream,
    -- but done in the middle of the data.
    --
    -- This has different meanings for different conversions. For instance
    -- in a compression converter it would mean that we flush all the
    -- compression state into output such that if you uncompress the
    -- compressed data you get back all the input data. Doing this may
    -- make the final file larger due to padding though. Another example
    -- is a regexp conversion, where if you at the end of the flushed data
    -- have a match, but there is also a potential longer match. In the
    -- non-flushed case we would ask for more input, but when flushing we
    -- treat this as the end of input and do the match.
    --
    -- Flushing is not always possible (like if a charset converter flushes
    -- at a partial multibyte sequence). Converters are supposed to try
    -- to produce as much output as possible and then return an error
    -- (typically 'GI.Gio.Enums.IOErrorEnumPartialInput').
