Enum DomainError 

pub enum DomainError {
    Io {
        context: &'static str,
        source: Error,
    },
    NotFound {
        entity: &'static str,
        id: String,
    },
    AmbiguousTarget {
        entity: &'static str,
        input: String,
        matches: String,
    },
}

Error type used by domain ports and domain utilities.

Variants

Source error.

NotFound

Requested entity was not found.

Fields

entity: &'static str

Entity kind.

id: String

Requested identifier.

AmbiguousTarget

Target was ambiguous and matched multiple entities.

input: String

User-provided target.

matches: String

Implementations

impl DomainError

pub fn io(context: &'static str, source: Error) -> Self

Build an IO-flavored domain error with a static context string.

pub fn not_found(entity: &'static str, id: impl Into<String>) -> Self

Build a not-found error for an entity.

pub fn ambiguous_target( entity: &'static str, input: &str, matches: &[String], ) -> Self

Build an ambiguity error for an entity target.

Trait Implementations

impl Debug for DomainError

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

Formats the value using the given formatter.

impl Display for DomainError

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

Formats the value using the given formatter.

impl Error for DomainError

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.
