Crate getter_methods

getter_methods is a derive macro that will implement accessor methods for each field on the struct.

Using getter_methods is straightforward: simply derive it:

use getter_methods::GetterMethods;

#[derive(GetterMethods)]
struct Foo {
  bar: String,
  baz: i64,
}

let foo = Foo { bar: "bacon".into(), baz: 42 };
assert_eq!(foo.bar(), "bacon");
assert_eq!(foo.baz(), 42);

Return types

Accessors will get a convenient return type depending on the type of the field on the struct:

Struct Field	Accessor Return Type
String	&str
Primitive T (e.g. i64)	T
Any other T	&T

Documentation

Any docstrings used on the fields are copied to the accessor method.

Skipping fields

If you don’t want a certain field to have an accessor method, annotate it:

use getter_methods::GetterMethods;

#[derive(GetterMethods)]
struct Foo {
  bar: String,
  #[getter_methods(skip)]
  baz: i64,
}

let foo = Foo { bar: "bacon".into(), baz: 42 }
assert_eq!(foo.bar(), "bacon");
assert_eq!(foo.baz(), 42);  // Compile error: There is no `foo.baz()`.
