Struct substreams_ethereum::Abigen

pub struct Abigen { /* private fields */ }

Builder struct for generating type-safe bindings Rust code directly in your project from a contract’s ABI. This is equivalent to code generated by macro use_contract.

Example

Running the code below will generate a file called erc721.rs containing the bindings inside, which exports an erc struct, along with all its events. Put into a build.rs file this will generate the bindings during cargo build.

    use anyhow::{Ok, Result};
    use substreams_ethereum::Abigen;

    fn main() -> Result<(), anyhow::Error> {
        Abigen::new("ERC721", "abi/erc721.json")?
            .generate()?
            .write_to_file("src/abi/erc721.rs")?;

        Ok(())
    }

pub fn new<S>(_contract_name: S, path: S) -> Result<Abigen, Error>where
    S: AsRef<str>,

Creates a new builder for the given contract name and where the ABI JSON file can be found at path, which is relative to the your crate’s root directory (where Cargo.toml file is located).
