convert-chain
A 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 c = C;
let a = convert_chain!(c; B, A);
Create a closure
rust
let c = C;
let f = convert_chain!(B, A);
let a = f(c);
Both of the above methods are equivalent to
rust
let c = C;
let a = A::from(A::from(c));
