Strongly Typed ID types macro

A macro to simplify usage of srongly type ID types instead of plain String, u64 or Guid in Rust codebases.

use stidgen::{Id, id};

#[id]
pub struct UserId(String);

#[id(NoDefaults, Format, Debug)]
pub struct UserId(u64);

While the derive macro can already be used to achieve most of what this macro proposes using it has the following advantages:

• It's simplier to use for well known types, simply add #[id] to your struct
• The defaults provide a lot of blanket implementations that might be missed when doing it manually
• Some features provided don't have corresponding derive macros (AsBytes, AsRef, Borrow)
• All trivial functions are marked inline

Settings

• Defaults/NoDefaults: Enable or disable defaults for known types
• Clone/NoClone: Enable or disable deriving std::clone::Clone
• Hash/NoHash: Enable or disable deriving std::hash::Hash
• PartialEq/NoPartialEq: Enable or disable deriving std::cmp::PartialEq
• Eq/NoEq: Enable or disable deriving std::cmp::Eq
• PartialOrd/NoPartialOrd: Enable or disable deriving std::cmp::PartialOrd
• Ord/NoOrd: Enable or disable deriving std::cmp::Ord
• Display/NoDisplay: Enable or disable deriving std::fmt::Display and adding a to_string method
• Debug/NoDebug: Enable or disable deriving std::fmt::Debug
• AsBytes/NoAsBytes: Enable or disable deriving std::convert::AsRef<[u8]> and adding a as_bytes method
• Borrow/NoBorrow: Enable or disable deriving std::borrow::Borrow
• AsRef/NoAsRef: Enable or disable deriving std::convert::AsRef

Default types

For unknown types all features are disabled by default but some types like String have smart defaults.

#[id(Clone, Hash, PartialEq, Eq, PartialOrd, Ord, Display, ToString, Debug, AsBytes, ...)]
pub struct Id(String);
