Enum NotifierError 

pub enum NotifierError {
    Io(String),
    Config(String),
    Service {
        status: u16,
        message: String,
    },
    Timeout {
        elapsed_ms: u64,
    },
    Unavailable(String),
}

Plugin-returned error type.

Every variant is treated identically by the engine: logged via tracing::warn!, recorded in ReactionOutcome { success: false, .. }, and never propagated up to the polling loop. A flaky notifier must not wedge the tick — matches the “never poison the engine” principle used for malformed durations in Slice 2 Phase H.

The variant split exists so plugin authors have a reasonable place to put their own errors without inventing a new enum per plugin. HTTP plugins lean on Service + Timeout; desktop plugins lean on Unavailable; anything that failed before the wire lean on Config or Io.

Variants

Io(String)

Local I/O failed — filesystem, stdout, named pipe, etc.

Config(String)

Plugin configuration is invalid or incomplete (missing token, unparseable URL, …).

Service

External service returned a non-success status.

Fields

status: u16

message: String

Timeout

Plugin exceeded its own timeout budget before the service responded.

Fields

elapsed_ms: u64

Unavailable(String)

External service or local dependency is unreachable right now (connection refused, DNS failure, desktop daemon missing).

Trait Implementations

impl Debug for NotifierError

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

Formats the value using the given formatter.

impl Display for NotifierError

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

Formats the value using the given formatter.

impl Error for NotifierError

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>)
