[−][src]Crate inspector
Crate inspector
extends popular data structures (such as Option
and Result
)
with additional methods for inspecting their payload. It is inspired by the Iterator::inspect
.
Since no such methods are available by default on Option
and Result
types, this crate
implements a new traits for these types, which augment the respective types with various
inspection capabilities.
Implementation and availability of each trait is guarded by the dedicated feature, so that
you can choose which one is available. Sometimes you want these only for debug purposes, but
prefer to always leave the code in place. Feature debug-only
helps in this case.
If enabled and compiled in release
mode the combinators become effectively NOP.
This feature does nothing in debug
mode.

Traits
FutureInspector | Do something with the error of a future, passing it on. This combinator was implemented in futures-0.2 series (which is now dead), but never made it back to futures-0.1.x series. |
