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.
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.
}
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;
...
};
}
```rs use multicall::multicall; use std::ops::AddAssign;
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/.
