Multicall

This library provides the multicall! macro, which allows you to apply multiple operations to one object without writing the name of the object again and again.

Syntax:

rs let mut test_variable = 1; multicall! { expr: operation; set test_variable = operation; exec normal_operation(#); operation; ... { subexpr: operation; set test_variable += operation; exec normal_operation(#); operation; ... }; // this semicolon is mandatory. }

Evaluates to:

rs let mut test_variable = 1; { let __multicall_item__ = expr; __multicall_item__.operation; test_variable = __multicall_item__.operation; normal_operation(__multicall_item__); __multicall_item__.operation; ... { let __multicall_item__ = __multicall_item__.subexpr; __multicall_item__.operation; test_variable += __multicall_item__.operation; normal_operation(__multicall_item__); __multicall_item__.operation; ... }; }

Example:

```rs use multicall::multicall; use std::ops::AddAssign;

[derive(Debug)]

struct Test { a: u32, b: i32 }

fn main() { let mut test = Test { a: 0, b: 0 }; let bplusfive; multicall! { &mut test: a = 5; b = 6; { b: addassign(500); }; { a: addassign(58); }; a.addassign(100 - 58); set bplus_five = b + 5; exec println!("{}, {}", #.a, #.b); } println!("{test:?}"); } ``` More in examples/.
