Enum httlib_hpack::decoder::DecoderError

pub enum DecoderError {
    InvalidInput,
    InvalidIndex,
    InvalidPrefix,
    IntegerOverflow,
    IntegerUnderflow,
    InvalidMaxDynamicSize,
}

Contains error options that can be encountered while performing the decoding of an HPACK header set.

Variants

InvalidInput

Indicates that the decoder received an invalid (Huffman) buffer. This should never happen if the input is encoded according to the HPACK spec.

InvalidIndex

Indicates that an invalid index was provided. According to the HPACK specification, the index 0 must be treated as an invalid index number. The first valid number is 1.

InvalidPrefix

Indicates that an invalid prefix was provided (must be [1, 8]).

IntegerOverflow

Indicates that the value of the integer being decoded exceeds a certain threshold (5 bytes are chosen by this implementation).

IntegerUnderflow

Indicates that the buffer from which an integer was supposed to be decode does not contain enough octets to complete the decoding.

InvalidMaxDynamicSize

Indicates that the decoder received a size that do not follow external protocol rules.

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

impl From<DecoderError> for DecoderError

fn from(err: HuffmanError) -> Self

Performs the conversion.

impl PartialEq<DecoderError> for DecoderError

fn eq(&self, other: &DecoderError) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
