Enum encoding_rs::DecoderResult
[−]
[src]
#[must_use]pub enum DecoderResult { InputEmpty, OutputFull, Malformed(u8, u8), }
Result of a (potentially partial) decode operation without replacement.
Variants
InputEmpty
The input was exhausted.
If this result was returned from a call where last
was true
, the
decoding process has completed. Otherwise, the caller should call a
decode method again with more input.
OutputFull
The decoder cannot produce another unit of output, because the output buffer does not have enough space left.
The caller must provide more output space upon the next call and re-push the remaining input to the decoder.
Malformed(u8, u8)
The decoder encountered a malformed byte sequence.
The caller must either treat this as a fatal error or must append one REPLACEMENT CHARACTER (U+FFFD) to the output and then re-push the the remaining input to the decoder.
The first wrapped integer indicates the length of the malformed byte sequence. The second wrapped integer indicates the number of bytes that were consumed after the malformed sequence. If the second integer is zero, the last byte that was consumed is the last byte of the malformed sequence. Note that the malformed bytes may have been part of an earlier input buffer.
The first wrapped integer can have values 1, 2 or 3. The second wrapped integer can have values 0, 1, 2 or 3. This makes the worst-case sum of the two 6, and the worst case actually happens with ISO-2022-JP.
