A macro to clone variables into the current scope shadowing old ones.
Help
If you run into any issues or need help with using shadow-clone
in your project please email incoming+efunb-shadow-clone-12722979-issue-@incoming.gitlab.com.
How to use
Add
= "1"
to your cargo.toml
under [dependencies]
and add
use shadow_clone;
to your main file.
Examples
let s = "foo".to_string;
let c = move |x: i32| format!;
let bar = s;
This will not compile as s
has been moved into the closure.
This issue can be solved with this macro.
use shadow_clone;
let s = "foo".to_string;
let bar = s;
That expands to,
use shadow_clone;
let s = "foo".to_string;
let bar = s;
You can also clone multiple variables separated by commas: shadow_clone!(foo, bar);
.
You can also bind a clone as mutable by prefixing with mut
: shadow_clone!(mut foo);
.
