Enum FrameError 

pub enum FrameError {
    ShortHeader,
    ShortPayload,
    PayloadTooLarge(u32),
    UnknownOp(u8),
    TruncatedPayload,
    InvalidUtf8,
    UnknownWireType(u8),
    FieldTooLarge,
}

Decode-side errors. Encode never produces these unless the caller exceeded MAX_PAYLOAD; see encode.

Variants

ShortHeader

Fewer than FRAME_HEADER_LEN bytes in the buffer.

ShortPayload

Header parsed, but the buffer ran out before the full payload arrived. The caller should accumulate more bytes and retry.

PayloadTooLarge(u32)

Declared payload length exceeds MAX_PAYLOAD.

UnknownOp(u8)

Opcode byte is not a known Op variant.

TruncatedPayload

Payload decoding ran past the end of the buffer.

InvalidUtf8

Payload bytes that were supposed to be UTF-8 weren’t.

UnknownWireType(u8)

Value-codec type tag byte is not a known WireType.

FieldTooLarge

A length field (column count, payload sub-length, …) overflowed its on-wire width — typically u16 for counts or u32 for text.

Trait Implementations

impl Clone for FrameError

fn clone(&self) -> FrameError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Eq for FrameError

impl PartialEq for FrameError

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