getset
Getset, we're ready to go!
A procedural macro for generating the most basic getters and setters on fields.
Getters are generated as fn field(&self) -> &type, while setters are generated as fn field(&mut self, val: type).
These macros are not intended to be used on fields which require custom logic inside of their setters and getters. Just write your own in that case!
#[macro_use]
extern crate getset;
#[derive(Getters, Setters, MutGetters, Default)]
pub struct Foo<T> where T: Copy + Clone + Default {
/// Doc comments are supported!
/// Multiline, even.
#[get] #[set] #[get_mut]
private: T,
/// Doc comments are supported!
/// Multiline, even.
#[get = "pub"] #[set = "pub"] #[get_mut = "pub"]
public: T,
}
fn main() {
let mut foo = Foo::default();
foo.set_private(1);
(*foo.private_mut()) += 1;
assert_eq!(*foo.private(), 2);
}Attributes can be set on struct level for all fields in struct as well. Field level attributes take precedence.
#[macro_use]
extern crate getset;
mod submodule {
#[derive(Getters, Default)]
#[get = "pub"] // By default add a pub getting for all fields.
pub struct Foo {
public: i32,
#[get] // Override as private
private: i32,
}
fn demo() {
let mut foo = Foo::default();
foo.private();
}
}
fn main() {
let mut foo = submodule::Foo::default();
foo.public();
}For some purposes, it's useful to have the get_ prefix on the getters for
either legacy of compatability reasons. It is done with get-prefix.
#[macro_use]
extern crate getset;
#[derive(Getters, Default)]
pub struct Foo {
#[get = "pub with_prefix"]
field: bool,
}
fn main() {
let mut foo = Foo::default();
let val = foo.get_field();
