field_access
A library for dynamic access to struct fields with #![no_std]
support.
Field access is enabled by the FieldAccess
trait which can be implemented
using a derive macro by the same name.
use field_access::FieldAccess;
#[derive(FieldAccess)]
struct Foo {
a: u8
}
let mut foo = Foo { a: 1 };
// Immutable field access.
if let Some(field) = foo.field("a") {
assert_eq!(field.as_u8(), Some(1));
}
// Mutable field access.
if let Some(mut field) = foo.field_mut("a") {
assert_eq!(field.replace(42u8), Some(1));
}
assert_eq!(foo.a, 42);
