Struct Contract

pub struct Contract {
    pub compiled_contract: CompiledContract,
}

Contract is a struct to interface with a contract. That includes things such as compiling, deploying, and running transactions against a contract.

Fields

compiled_contract: CompiledContract

Implementations

impl Contract

pub fn new(compiled_contract: CompiledContract) -> Self

pub fn compute_contract_id(compiled_contract: &CompiledContract) -> ContractId

pub async fn call( contract_id: ContractId, encoded_selector: Option<Selector>, encoded_args: Option<Vec<u8>>, fuel_client: &FuelClient, gas_price: Word, gas_limit: Word, maturity: Word, custom_inputs: bool, ) -> Result<Vec<Receipt>, String>

Calls an already-deployed contract code. Note that this is a “generic” call to a contract and it doesn’t, yet, call a specific ABI function in that contract.

pub fn method_hash<D: Detokenize>( fuel_client: &FuelClient, compiled_contract: &CompiledContract, signature: Selector, output_params: &[ParamType], args: &[Token], ) -> Result<ContractCall<D>, Error>

Creates an ABI call based on a function selector and the encoding of its call arguments, which is a slice of Tokens. It returns a prepared ContractCall that can further be used to make the actual transaction. This method is the underlying implementation of the functions generated from an ABI JSON spec, i.e, this is what’s generated: quote! { #doc pub fn #name(&self #input) -> #result { Contract::method_hash(#tokenized_signature, #arg) } } For more details see code_gen/functions_gen.rs.

pub async fn launch_and_deploy( compiled_contract: &CompiledContract, ) -> Result<(FuelClient, ContractId), Error>

Launches a local fuel-core network and deploys a contract to it. If you want to deploy a contract against another network of your choosing, use the deploy function instead.

pub async fn deploy( compiled_contract: &CompiledContract, fuel_client: &FuelClient, ) -> Result<ContractId, Error>

Deploys a compiled contract to a running node

pub fn compile_sway_contract( project_path: &str, salt: Salt, ) -> Result<CompiledContract, Error>

Compiles a Sway contract

pub fn contract_deployment_transaction( compiled_contract: &CompiledContract, ) -> (Transaction, ContractId)

Crafts a transaction used to deploy a contract
