Enum httlib_huffman::decode::DecoderError

pub enum DecoderError {
    InvalidInput,
    BufferOverflow,
    InvalidSpeed,
}

An object returned by the decode function when an error occurs.

Variants

InvalidInput

Indicates that the decoder received an invalid Huffman code. This should never happen in the input is encoded according to the HPACK spec.

BufferOverflow

Indicates that the available space has been filled in full. This happens when the decode function is not called often enough. Call the decode function immediately after the buffer is appended to avoid this issue.

InvalidSpeed

Indicates that the decoder received an invalid value for the speed attribute. This attribute tells the encoder how many bits at a time should be read to decode a sequence. The expected value is between 1 and 5.

Trait Implementations

impl Debug for DecoderError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DecoderError

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DecoderError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
