unbox-box
This crate provides .unbox_ref()
and .unbox_mut()
methods on Box
types. They are equivalent to .deref()
and .deref_mut()
, but make it easier to see that the variable that is being operated on is of type Box
.
Usage
The idea for this crate came to me this morning when I woke up to this code
let expr: &syn::ExprLit = match &*assignment.expr { ... };
and was very unsure as to why there was a deref operator *
in front of my variable. Now I just import
unbox-box = "0.1"
and I can replace this code with
use unbox_box::BoxExt as _;
let expr: &syn::ExprLit = match assignment.expr.unbox_ref() { ... };
When I wake up to this code tomorrow, I'm pretty sure I'll recognize that assignment.expr
is a Box
. Wish me luck!
