Expand description
If the given expression is a local binding, find the initializer expression. If that initializer expression is another local binding, find its initializer again.
This process repeats as long as possible (but usually no more than once). Initializer
expressions with adjustments are ignored. If this is not desired, use find_binding_init
instead.
Examples:
let abc = 1;
// ^ output
let def = abc;
dbg!(def);
// ^^^ input
// or...
let abc = 1;
let def = abc + 2;
// ^^^^^^^ output
dbg!(def);
// ^^^ input
