pub struct Abigen { /* private fields */ }

Implementations

impl Abigen

pub fn new<S: AsRef<str>>( contract_name: &str, abi_source: S, ) -> Result<Self, Error>

Creates a new contract with the given ABI JSON source.

pub fn no_std(self) -> Self

pub fn generate(self) -> Result<ContractBindings, Error>

Generates the contract bindings.

pub fn expand(&self) -> Result<TokenStream, Error>

Entry point of the Abigen’s expansion logic. The high-level goal of this function is to expand* a contract defined as a JSON into type-safe bindings of that contract that can be used after it is brought into scope after a successful generation.

*: To expand, in procedural macro terms, means to automatically generate Rust code after a transformation of TokenStream to another set of TokenStream. This generated Rust code is the brought into scope after it is called through a procedural macro (abigen!() in our case).
