Enum ReplicationWireError 

pub enum ReplicationWireError {
    Truncated {
        need: usize,
        have: usize,
    },
    SubprotocolMismatch {
        got: u16,

    BadRole(u8),
    BadErrorCode(u8),

}

Errors surfacing from the decode path. Mirrors the typed-error shape the rest of the substrate uses for fallible decoders.

Variants

Truncated

Buffer is shorter than the encoded message demands.

Fields

need: usize

Minimum bytes the decoder needed to make progress.

have: usize

Bytes actually available in the input.

SubprotocolMismatch

Subprotocol header doesn’t match SUBPROTOCOL_REDEX.

Fields

got: u16

Subprotocol id observed in the header.

DispatchMismatch

Dispatch code doesn’t match the decoder being invoked, or falls outside the reserved 0x20..=0x2F range entirely.

Fields

got: u8

Dispatch byte observed in the header.

expected: u8

Dispatch byte the decoder being invoked is keyed on.

BadRole(u8)

role byte in a SyncHeartbeat is outside the 0..=3 range the four-state model pins.

BadErrorCode(u8)

error_code byte in a SyncNack is outside the 1..=4 range the typed-error variants pin.

InvalidUtf8

detail bytes in a SyncNack are not valid UTF-8.

Trait Implementations

impl Debug for WireError

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

Formats the value using the given formatter.

impl Display for WireError

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

Formats the value using the given formatter.

impl Eq for WireError

impl Error for WireError

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 WireError

fn eq(&self, other: &WireError) -> 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.
