documentation

optfield is a macro that, given a struct, generates another struct with the same fields, but wrapped in Option<T>.

Minimum rustc version: 1.61.0

cargo add optfield

optfield takes the opt struct name as its first argument:

use optfield::optfield;

#[optfield(Opt)]
struct MyStruct<T> {
    text: String,
    number: i32,
    generic: T,
}

This will generate another struct that looks like:

struct Opt<T> {
    text: Option<String>,
    number: Option<i32>,
    generic: Option<T>,
}

optfield supports defining visibility, documentation, attributes and merge methods. For more details and examples check its documentation.
