Namespace Olve.Results

Classes

DeletionResultExtensions: Extension methods for DeletionResult.

DictionaryResultExtensions: Extension methods for dictionary operations that return Result instead of throwing.

ErrorCaseAttribute: Marks a static partial factory method on a GenerateResultAttribute type as an error case. Error cases contribute to Failed and carry problems.

GenerateResultAttribute: Marks a partial struct for which Olve.Results generates multi-state result boilerplate. Each state is declared as a static partial factory method annotated with SuccessCaseAttribute, ErrorCaseAttribute or GreyCaseAttribute. The generator emits the factory bodies, a state discriminator, per-case Is… predicates, Succeeded/Failed, and an exhaustive Match.

GreyCaseAttribute: Marks a static partial factory method on a GenerateResultAttribute type as a grey case: a state that is neither success nor failure (e.g. not-found). Grey cases make both Succeeded and Failedfalse.

MustBeUsedWhenReturnedAttribute: Marks a type whose values must always be observed when returned from a method. The Olve.Results analyzer (ORES001) reports a diagnostic when a method that returns an annotated type (directly or wrapped in Task<TResult> / ValueTask<TResult>) is invoked as a statement without observing the result.

NotFoundProblem: A problem signalling that the thing an operation needed does not exist (an unknown id or key). Transports can recover it by type, e.g. Olve.MinimalApi answers 404 Not Found.

ResultEnumerableExtensions: Extension methods for working with Result, Result, and Result<T> collections.

ResultExtensions: Extension methods for Result and Result<T>.

ResultFuncExtensions: Extensions for Func<T, TResult>.

ResultProblem: Represents a problem encountered during an operation.

ResultProblemCollection: Represents a collection of problems encountered during an operation.

SuccessCaseAttribute: Marks a static partial factory method on a GenerateResultAttribute type as a success case. Success cases contribute to Succeeded.

Structs

DeletionResult: Represents the result of a deletion operation, which can succeed, fail due to not being found, or fail due to an error.

ProblemOriginInformation: Represents the origin of a problem.

Result: Represents a result of an operation without a value, indicating success or failure.

Result<T>: Represents a result of an operation with a value, indicating success or failure.

Interfaces

IResultType: Common interface implemented by Result and Result<T> to enable non-reflective type checking and value extraction.
