Enum EncoderError 

pub enum EncoderError {
    InvalidInput,
    InvalidIndex,
    InvalidPrefix,
    IntegerOverflow,
}

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

Variants

InvalidInput

Indicates that the encoder received an invalid ASCII character and is thus unable to perform the (Huffman) encoding. Note that only ASCII characters provided in the HPACK spec should be used.

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 encoded exceeds a certain threshold (5 bytes are chosen by this implementation). This can also happen while encoding too long string.

Trait Implementations

impl Debug for EncoderError

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

Formats the value using the given formatter.

impl Display for EncoderError

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

Formats the value using the given formatter.

impl Error for EncoderError

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

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<EncoderError> for EncoderError

fn from(err: HuffmanError) -> Self

Converts to this type from the input type.

impl PartialEq for EncoderError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
