Enum PreambleError 

pub enum PreambleError {
    Incomplete,
    BadMagic(u8),
    UnknownKind(u8),
    HeaderTooLarge {
        len: u64,
        max: u64,
    },
}

Why a preamble was rejected.

Variants

Incomplete

Not enough bytes yet. Read more and retry; not a protocol violation.

BadMagic(u8)

The first byte was not MAGIC.

UnknownKind(u8)

The kind byte is not defined in this protocol version.

HeaderTooLarge

The advertised header length exceeds the local cap. Reported before any allocation is attempted.

Fields

len: u64

Length the peer advertised.

max: u64

Local cap that was exceeded.

Implementations

impl PreambleError

pub const fn is_violation(self) -> bool

True if the error is fatal for the connection. Only PreambleError::Incomplete is not.

Trait Implementations

impl Clone for PreambleError

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 PreambleError

impl Debug for PreambleError

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

Formats the value using the given formatter.

impl Display for PreambleError

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

Formats the value using the given formatter.

impl Eq for PreambleError

impl Error for PreambleError

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 PreambleError

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

Equality operator ==.

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

Inequality operator !=.
