Enum Error 

pub enum Error {
    Truncated,
    IntegerOverflow,
    InvalidIndex,
    Huffman,
    InvalidTableSizeUpdate,
    HeaderListTooLarge,
}

HPACK decoding errors. Every error except Error::HeaderListTooLarge leaves the decoder out of step with the peer’s encoder and maps to the HTTP/2 connection error COMPRESSION_ERROR.

Variants

Truncated

The block ends in the middle of a representation.

IntegerOverflow

A prefix integer is too large.

InvalidIndex

An index outside the static and dynamic tables (or index 0).

Huffman

Invalid Huffman data: EOS in the string, bad or overlong padding.

InvalidTableSizeUpdate

A dynamic table size update above the allowed maximum or after the first field.

HeaderListTooLarge

The decoded list is larger than the cap. The block was still decoded completely, so the decoder stays in step with the encoder and the connection can continue; fields after the limit were not passed to the callback.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
