Struct NotFound 

pub struct NotFound {
    pub entity: &'static str,
    pub column: Option<&'static str>,
    pub value: String,
}

A repo op that requires a row (find_by_*) found none. There is no NotFound rejection — callers that tolerate absence use maybe_find_by_*, which returns Option instead. Construct one and propagate it with ?: it converts into any errlanes::Fault or errlanes::Fail<D> as Fatal(Invariant).

Never impl errlanes::Rejection for NotFound — #[derive(Classify)] below makes NotFound a fault wrapper, and a type that is both a Rejection and a direct Classify impl conflicts (E0119).

Security note: value’s Debug may contain PII (e.g. an email address looked up by a caller-supplied value). Display omits it.

Implementations

impl NotFound

pub fn new( entity: &'static str, column: Option<&'static str>, value: impl Into<String>, ) -> Self

Trait Implementations

impl Classify for NotFound

type Rejected = !

type Lanes = Profile<false, false, true>

fn classify(self) -> Fail<Self::Rejected, Self::Lanes>

impl Debug for NotFound

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

Formats the value using the given formatter.

impl Display for NotFound

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

Formats the value using the given formatter.

impl Error for NotFound

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>)
