tryFuture(_:)

An alternate name for this would be future(catching:), but with that name, trailing closure syntax just looks like el.future { ... }, which does not indicate to readers of the code that it is the error-capturing version. Since such an indication is highly desirable, a slightly less idiomatic name is used instead.

EventLoopGroup+Throwing.swift:26
func tryFuture<T>(_ work: @escaping () throws -> T) -> EventLoopFuture<T>

Parameters

work

The potentially throwing closure to execute as a future. If the closure throws, a failed future is returned.

This method replaces this code:

return something.eventLoop.future().flatMapThrowing {

With this code:

return something.eventLoop.tryFuture {

That’s pretty much it. It’s sugar.
