Disconnected

Shutdown

PutCallbackInProgress(String)

CA WRITE_NOTIFY arrived while a previous async put on the same record is still in flight. Mirrors C EPICS S_db_Blocked; the CA server replies ECA_PUTCBINPROG.

ServerError(u32)

Server-emitted ECA status carried out-of-band on an otherwise data-shaped frame — used by libca cac::eventAddRespAction (cac.cpp:973-977) when a monitor frame’s m_cid is non- NORMAL (e.g. ECA_NORDACCESS from no_read_access_event after an ACF reload). Routed to the per-subscription callback as Err(CaError::ServerError(eca_status)) so the subscriber surfaces the status instead of seeing the bogus zeroed payload that travels with the frame.

Implementations

impl CaError

pub fn to_eca_status(&self) -> u32

Trait Implementations

impl Debug for CaError

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

Formats the value using the given formatter.

impl Display for CaError

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

Formats the value using the given formatter.

impl Error for CaError

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<Error> for CaError

fn from(source: Error) -> CaError

Converts to this type from the input type.
