Enum ProtocolViolation 

#[non_exhaustive]
pub enum ProtocolViolation {
    EmptyRequest,
    AddressOverflow(InputRequest),
    NoProgress(InputRequest),
    NeedPastEnd {
        request: InputRequest,
        total: u64,
    },
}

A decoder broke the IncrementalDecode protocol. Drivers report this instead of looping.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyRequest

Need with no requests.

AddressOverflow(InputRequest)

A request’s offset plus length cannot be represented by the protocol.

NoProgress(InputRequest)

The input satisfied one of the decoder’s requests, yet it took nothing and asked again.

NeedPastEnd

The decoder asked for bytes past the end it was told about, instead of reporting truncated input.

Fields

request: InputRequest

The request.

total: u64

The total length the decoder had been given.

Trait Implementations

impl Clone for ProtocolViolation

fn clone(&self) -> ProtocolViolation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolViolation

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

Formats the value using the given formatter.

impl Display for ProtocolViolation

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

Formats the value using the given formatter.

impl Eq for ProtocolViolation

impl Error for ProtocolViolation

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 ProtocolViolation

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

Equality operator ==.

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

Inequality operator !=.
