Struct ApplicationError 

#[non_exhaustive]
pub struct ApplicationError {
    stage: ApplicationStage,
    kind: ApplicationErrorKind,
}

Typed, intentionally opaque failure from an application-layer use case.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

stage: ApplicationStage

kind: ApplicationErrorKind

Implementations

impl ApplicationError

pub fn from_engine(stage: ApplicationStage, source: EngineError) -> Self

Wraps a lower engine failure with its stage; a deliberate non-blanket alternative to From<EngineError>.

pub(crate) fn encounter_resolution( stage: ApplicationStage, source: EncounterResolutionError, ) -> Self

pub(crate) fn intent_config( stage: ApplicationStage, source: IntentConfigError, ) -> Self

pub(crate) fn spec_construction_resolver( stage: ApplicationStage, context: &'static str, source: ResolverError, ) -> Self

pub const fn stage(&self) -> ApplicationStage

pub const fn category(&self) -> ApplicationErrorCategory

pub const fn encounter_resolution_error( &self, ) -> Option<&EncounterResolutionError>

pub const fn resolver_error(&self) -> Option<&ResolverError>

Trait Implementations

impl Debug for ApplicationError

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

Formats the value using the given formatter.

impl Display for ApplicationError

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

Formats the value using the given formatter.

impl Error for ApplicationError

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.
