Crate try_blocks

Macro for stable try blocks that performs Ok-wrapping, and otherwise tries to achieve feature parity with RFC 1859. The macro is compatible with any type that implements the unstable Any trait through the use of type magic.

This crate is a fork of try-block, which has not been updated in four years at the time of writing this. This fork adds Ok-wrapping and the promise of future updates.

This crate is no_std compatible.

Macros

try_block

Macro for the recieving end of a ? operation. Right now, type inference is quite finicky so you usually have to declare a concrete type somewhere.

try_cf

Like try_block, but specificially for [ControlFlow]. This aids type inference.

try_opt

Like try_block, but specificially for Option. This aids type inference.

try_res

Like try_block, but specificially for Result]. This aids type inference.

wrap_ok

Macro for ok-wrapping any Try type. This works on stable through dark type magic.
