Enum Error 

pub enum Error {
    BufferTooShort {
        need: usize,
        have: usize,
    },
    TrailingBytes {
        expected: usize,
        actual: usize,
    },
    UnknownVersion(u8),
    UnknownMsgType(u8),
    UnknownCryptoSuite(u8),
    PayloadTooLarge(usize),
}

Errors that can occur during ZCP envelope encoding or decoding.

Variants

BufferTooShort

Input buffer is too short to contain the expected data.

Fields

need: usize

Minimum bytes needed.

have: usize

Bytes actually available.

TrailingBytes

Buffer contains extra bytes after the complete envelope.

Fields

expected: usize

Expected total frame size.

actual: usize

Actual buffer size.

UnknownVersion(u8)

Unknown protocol version byte.

UnknownMsgType(u8)

Unknown message type byte (not in any allocated range).

UnknownCryptoSuite(u8)

Unknown crypto suite identifier.

PayloadTooLarge(usize)

Payload exceeds maximum encodable size (> u32::MAX bytes).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Error for Error

Available on crate feature std only.

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: &Error) -> 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.
