convert-chainA tiny crate for chain type converter. There is only one macro convert_chian in it
Assuming there are 3 sturct with following relationship. ```rust struct A; struct B; struct C;
impl From for A { ... }
impl From
You can use the macro to directly convert an expression or create a closure for the convert.
Directly convert
rust
let a = A;
let C = convert_chain!(c; B, C);
Create a closure
rust
let a = A;
let f = convert_chain!(B, C);
let c = f(C);
Both of the above methods are equivalent to
rust
let a = A;
let c = C::from(B::from(a));
