starknet-types-core

Core types representation for Starknet.

Overview

The starknet-types-core crate provides:

The universal Felt (Field Element) type for Cairo and STARK proofs. It was created to reduce the fragmentation in the Starknet Rust ecosystem by providing a standardized representation of the Felt type.

Features

Always on

Standardized Felt type: Simplify your codebase by using our standardized Felt type. Optimized for performance: The Felt type has been optimized for high-performance applications.
No_std support ✅

Serde

Provides a Serialization and Deserialization implementations for the Felt type
No_std support ✅

Parity Scale Codec

Provides Serialization and Deserialization implementations for the Felt type within the Parity serialization framework
No_std support ✅

Arbitrary

Provides an Arbitrary implementations for the Felt type

Curve

Add the AffinePoint and ProjectivePoint structs, which represent points on the Stark curve for performing elliptic curve operations.
No_std support ✅

Hash

Implements Pedersen hashing for Felts and Felts array

Examples

Here are some examples of how to use the starknet-types-core types:

    let felt = Felt::from(18);
    let projective_point = ProjectivePoint::new(Felt::from(0), Felt::from(1), Felt::from(0));
    let affine_point = AffinePoint::new(Felt::from(0), Felt::from(1)).unwrap();

Usage

Include starknet-types-core in your library by adding the following to your Cargo.toml:

    "alloc",
    "serde",
    "arbitrary",
    "curve",
    "hash",
] }
