Enum PacketFrameError 

pub enum PacketFrameError {
    Header(PacketHeaderError),
    InvalidMaxPacketSize(usize),
    MismatchedPacketType {
        expected: PacketType,
        actual: PacketType,
    },
    UnexpectedPacketId {
        expected: u8,
        actual: u8,
    },
    MessageTooLarge,
}

Error returned while framing or deframing TDS packets.

Variants

Header(PacketHeaderError)

Packet header decoding failed.

InvalidMaxPacketSize(usize)

The requested packet size cannot be encoded in a TDS packet header or leaves no room for payload bytes.

MismatchedPacketType

A decoded message contained packets with different packet types.

Fields

expected: PacketType

Packet type from the first packet.

actual: PacketType

Packet type from a later packet in the same message.

UnexpectedPacketId

Packet IDs in a multi-packet message were not contiguous.

Fields

expected: u8

Expected packet ID.

actual: u8

Packet ID from the header.

MessageTooLarge

The message could not fit in memory or in a protocol length field.

Trait Implementations

impl Debug for PacketFrameError

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

Formats the value using the given formatter.

impl Display for PacketFrameError

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

Formats the value using the given formatter.

impl Error for PacketFrameError

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 From<PacketFrameError> for Login7Error

fn from(source: PacketFrameError) -> Self

Converts to this type from the input type.

impl From<PacketFrameError> for PreLoginError

fn from(source: PacketFrameError) -> Self

Converts to this type from the input type.

impl From<PacketHeaderError> for PacketFrameError

fn from(source: PacketHeaderError) -> Self

Converts to this type from the input type.

impl PartialEq for PacketFrameError

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