Crate nft_image_and_metadata_generator

NFT image and metadata generator for Ethereum and Solana

Inspired by hashlips ‘nft_image_and_metada_generator’ provides functionality to generate NFT images as well as their respective metadata for both the Ethereum and Solana network. Note that this is the initial release, subsequent releases will contain performance improvements and general code optimizations.

Example of how to generate NFT images and metadata.

The following code demonstrates how to generate the NFT images along with metadata.

use nft_image_and_metadata_generator::{
    metadata::{Creator, MetadataHeader},
    ImageGenerator, Network,
};

fn main() {
    let collection_name = String::from("Test collection");
    let symbol = "TestSymbol";
    let description = "A test for generating NFT images along with the metadata.";
    let seller_fee_basis_points: u32 = 1000; // Define how much % you want from secondary market sales 1000 = 10%
    let external_url = "https://www.rust-lang.org/";
    let base_uri = "ipfs://NewUriToReplace"; // Not important for sol
    let address1 = "7fXNuer5sbZtaTEPhtJ5g5gNtuyRoKkvxdjEjEnPN4mC";
    let share1: u8 = 50;
    let creator1: Creator = Creator::new(address1, share1);
    let address2 = "99XNuer5sbZtaTEPhtJ5g5gNtuyRoKkvxdjEjEnPN4mC";
    let share2: u8 = 50;
    let creator2: Creator = Creator::new(address2, share2);
    let creators: Vec<Creator> = vec![creator1, creator2];
    let metadata: MetadataHeader = MetadataHeader::new(
        collection_name,
        symbol,
        description,
        seller_fee_basis_points,
        external_url,
        creators,
    );

    let path = "../layers";
    let output_path = "./output";
    let network = Network::Sol;
    let layer_order = vec![
        "Background",
        "Eyeball",
        "Eye color",
        "Goo",
        "Iris",
        "Shine",
        "Bottom lid",
        "Top lid",
    ];

    let layer_exclusion_probability = vec![0.0, 0.8, 0.0, 0.8, 0.5, 0.0, 0.0, 0.0];

    let delimeter = '#';
    let num_assets: u64 = 5;

    let mut img = ImageGenerator::new(
        path,
        output_path,
        network,
        base_uri,
        layer_order,
        Option::Some(layer_exclusion_probability),
        num_assets,
        delimeter,
        metadata,
    );
    img.generate();
}

Modules

metadata

A collection of structs which will be used to build the metadata for the NFTs. The only structs that the user needs to care about is MetadataHeader and Creator.

Structs

ImageGenerator

ImageGenerator struct is used to generate the NFTs and respective metadata. Attributes for the ImageGenerator struct:

Enums

Network

Enum to distinguish between the Ethereum and Solana networks
