Methods

ExecuteCore<TResult, TState>(Func<ResilienceContext, TState, ValueTask<Outcome<TResult>>>, ResilienceContext, TState)

An implementation of a proactive resilience strategy that executes the specified callback.

protected abstract ValueTask<Outcome<TResult>> ExecuteCore<TResult, TState>(Func<ResilienceContext, TState, ValueTask<Outcome<TResult>>> callback, ResilienceContext context, TState state)

Parameters

callback Func<ResilienceContext, TState, ValueTask<Outcome<TResult>>>: The user-provided callback.
context ResilienceContext: The context associated with the callback.
state TState: The state associated with the callback.

Returns

ValueTask<Outcome<TResult>>: An instance of a pending ValueTask for asynchronous executions or a completed ValueTask task for synchronous executions.

Type Parameters

TResult: The type of result returned by the callback.
TState: The type of state associated with the callback.

Remarks

The provided callback never throws an exception. Instead, the exception is captured and converted to an Outcome<TResult>. Similarly, do not throw exceptions from your strategy implementation. Instead, return an exception instance as Outcome<TResult>.
