Crate block_effects

With block_effects, it is possible to chain different block effects with the use of the block! macro.

This idea was proposed by mcy.

Goal

The main purpose of this crate is to minimize indentation for nested blocks. Unfortunately proc macros also add indentation. So to fully benefit from this one should not indent the block! macro or even put the macro braces on the same line as the block.

Example

 use block_effects::block;

 block!{
 if let Some(_) = Some(0) if let Some(_) = Some(0) {
     assert!(true); 
 }
 }

 let _future = block!{ unsafe async for i in 0..3 match i { 
     0..=2 => assert!(true),
     _ => assert!(false)
 } };

Macros

block

The block! macro is used to mark blocks with chained block effects.
