Rust Amplify Library

Amplifying Rust language capabilities: multiple generic trait implementations, type wrappers, derive macros.

Minimum supported rust compiler version (MSRV): 1.46 (stable channel)

Main features

Derive macros

• Display
• From
• Error
• Getters
• AsAny

A sample of what can be done with the macros: ```rust

[derive(From, Error, Display, Debug)]

[display(doc_comments)]

pub enum Error { // You can specify multiple conversions with separate attributes #[from(::std::io::Error)] #[from(IoError)] /// Generic I/O error Io,

#[from]
// This produces error description referencing debug representation
// of the internal error type
/// Formatting error: {_0:}
Format(::std::fmt::Error),

#[from]
/// Some complex error, here are details: {details}
WithFields { details: ::std::str::Utf8Error },

#[display(LowerHex)]
MultipleFields {
    // ...and you can also covert error type
    #[from(IoErrorUnit)]
    // rest of parameters must implement `Default`
    io: IoError,

    #[display(ToHex::to_hex)]
    details: String,
},

} ```

See more in amplify_derive crate README.

Macros

• s! for fast &str -> String conversions
• Collection-generating macros:
  • map! & bmap! for a rappid HashMap and BTreeMap creation
  • set! & bset! for a rappid HashSet and BTreeSet creation
  • list! for LinkedList

Generics

Library proposes generic implementation strategies, which allow multiple generic trait implementations. See src/strategy.rs mod for the details.
