small_read_only

This crate adds #[derive(ReadOnly)].
It implements getters for all fields without the #[NoRead] attribute.

It works for:

• Structs

Example

use small_read_only::ReadOnly;

#[derive(ReadOnly)]
pub struct A<'a> {
    b: usize,
    c: String,
    d: &'a str,
}

impl<'a> A<'a> {
    pub fn new(b: usize, c: String, d: &'a str) -> Self {
        Self {
            b, c, d
        }
    }
}

let a = A::new(1, "c".to_string(), "d");

assert_eq!(a.b(), &1);
assert_eq!(a.c(), "c");
assert_eq!(a.d(), &"d");

Example

use small_read_only::ReadOnly;

#[derive(ReadOnly)]
pub struct A<'a> {
    b: usize,
    c: String,
    d: &'a str,
}

impl<'a> A<'a> {
    pub fn new(b: usize, c: String, d: &'a str) -> Self {
        Self {
            b, c, d
        }
    }
}

let a = A::new(1, "c".to_string(), "d");

assert_eq!(a.b(), &1);
assert_eq!(a.c(), "c");
assert_eq!(a.d(), &"d");

NoRead attribute

#[derive(ReadOnly)]
pub struct B {
    #[NoRead]
    b: usize,
}

impl B {
    pub fn new(b: usize) -> Self {
        Self {
            b
        }
    }
}

let b = B::new(1);
b.b();
