#923 in Procedural macros
21KB
350 lines
rust-typed
Typed
is a procedural macro that is used for disassembling structs
and fns
into their inner type
components that are then accompanied with documentation and examples. The Typed
structures will be wrapped into a module and reassigned with a name (default core
), this also goes for the static
and generic
fields.
Project is still under development
Struct example
#[type_it]
struct Containter<T> {
current: u8,
buffer: Vec<u8>,
another: T,
}
#[type_it]
struct Area(i32);
- Will let you access the struct types as followed:
let current: Container::current = 10;
let buffer: Container::buffer = vec![current];
let another: <Container::core<u8> as Container::protocol>::another = 20;
let container: Container::core<u8> =
Container::core {
current,
buffer,
another
};
- It's also possible to use it as following:
trait Trait: Container::protocol {
fn retrieve(&self) -> Container::protocol::buffer;
fn extend(&mut self, val: Container::protocol::another);
}

#[type_it]
struct Container<C: Clone, T = i64> {
a: i32,
b: Vec<i32>,
c: Vec<T>,
d: C,
e: T
}
#[type_it]
struct Tuple(i32, i32);
#[type_it]
struct Tuple2<T>(i32, T);
fn main() {
let a: Container::fields::a = 10;
let b: Container::b = vec![a];
let c: Container::c<i64> = vec![10];
let c: <Container::core<i64> as Container::protocol>::c = c;
let d: <Container::core<i64> as Container::protocol>::d = 10;
let container: Container::core<i64> = Container::core { a, b, c, d, e: 10 };
assert!(container.a == a);
}
Disassembler
#[type_it]
struct #name {
#(#ident: #ty)*
}
// Turns into
#[allow(non_snake_case)]
// Docs (/w examples) describing the original `item` and also what `types` are available to use.
#[doc = #docs]
pub mod #name {
#![allow(non_camel_case_types)]
// The static fields of the `item` as type aliases.
#(#ty_decls)* // Access through `#name::#field`
// A trait where all `ìtem` fields are associated types
#struct_generic // Access through `#name::gen`
// Docs (/w examples) describing the original `item`.
#[doc = #docs]
// The original `ìtem`.
#struct_original // Access through `#name::core`
}
Future plans
Renaming disassembler
#[type_it = "MContainer"]
struct Containter<T> {
current: u8,
buffer: Vec<u8>,
another: T,
}
fn main() {
let x: Container<i32> = {
current: 10,
buffer: Vec::default(),
another: 20,
}
let y: MContainer::core<i32> = x;
}
