Enum SyncError 

pub enum SyncError {
    Transport(String),
    Handshake(String),
    Serialization(String),
    Timeout,
    ConnectionLost,
    ProtocolVersion {
        local: u32,
        remote: u32,
    },
    InvalidPayload(String),
    CursorNotFound {
        instance: InstanceId,
    },
    Shutdown,
}

Available on crate feature sync only.

Errors specific to the sync protocol.

These are wrapped into crate::PulseDBError::Sync when propagated through the public API.

Variants

Transport(String)

Transport-level failure (network I/O, connection refused, etc.).

Handshake(String)

Handshake was rejected by the remote peer.

Serialization(String)

Failed to serialize or deserialize a sync message.

Timeout

Operation timed out waiting for a response.

ConnectionLost

Connection to the remote peer was lost.

ProtocolVersion

Protocol version mismatch between peers.

Fields

local: u32

Local protocol version.

remote: u32

Remote protocol version.

InvalidPayload(String)

Received an invalid or unrecognized payload.

CursorNotFound

No cursor found for the specified peer instance.

Fields

instance: InstanceId

The peer instance whose cursor was not found.

Shutdown

The sync system is shutting down.

Implementations

impl SyncError

pub fn transport(msg: impl Into<String>) -> Self

Creates a transport error with the given message.

pub fn handshake(msg: impl Into<String>) -> Self

Creates a handshake error with the given message.

pub fn serialization(msg: impl Into<String>) -> Self

Creates a serialization error with the given message.

pub fn invalid_payload(msg: impl Into<String>) -> Self

Creates an invalid payload error with the given message.

pub fn is_transport(&self) -> bool

Returns true if this is a transport error.

pub fn is_timeout(&self) -> bool

Returns true if this is a timeout error.

pub fn is_connection_lost(&self) -> bool

Returns true if this is a connection lost error.

pub fn is_shutdown(&self) -> bool

Returns true if this is a shutdown error.

Trait Implementations

impl Debug for SyncError

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

Formats the value using the given formatter.

impl Display for SyncError

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

Formats the value using the given formatter.

impl Error for SyncError

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<Box<ErrorKind>> for SyncError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<SyncError> for PulseDBError

fn from(source: SyncError) -> Self

Converts to this type from the input type.
