Enum NotifyError 

pub enum NotifyError {
    UnknownCategory(String),
    InvalidData,
    NotMounted,
    MissingPort(&'static str),
    NoCatalog(String),
    Database(DbError),
}

Why a fan-out could not be prepared.

Variants

UnknownCategory(String)

The category is not one the venture declared. A typo in a caller is a bug, not a silent no-op.

InvalidData

Notification::data is neither absent nor a JSON object, so the module cannot add category and notification_id to it.

NotMounted

The module’s router has not been built yet, so it has no ports.

MissingPort(&'static str)

A port the module requires is absent from this deployment.

NoCatalog(String)

A Message::Localizable was sent to a venture that configured no catalog (#190). An error rather than an English fallback: the venture named a message it has no strings for, and delivering the id to a person is worse than telling the developer now.

Database(DbError)

Trait Implementations

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<DbError> for NotifyError

fn from(err: DbError) -> Self

Converts to this type from the input type.
