Derive Macro ethers_contract_derive::EthCall
source · #[derive(EthCall)]
{
// Attributes available to this derive:
#[ethcall]
}
Expand description
Derives the EthCall
and Tokenizeable
trait for the labeled type.
Additional arguments can be specified using the #[ethcall(...)]
attribute:
For the struct:
name = "..."
: Overrides the generated function name. Defaults to the struct’s name;abi = "..."
: The ABI signature of the function.
NOTE: in order to successfully parse the abi
(<name>(<args>,...)
), <name>
must match
either the struct’s name or the name attribute: #[ethcall(name = "<name>"]
§Examples
ⓘ
use ethers_contract_derive::EthCall;
use ethers_core::abi::{Address, FunctionExt};
#[derive(EthCall)]
#[ethcall(name = "my_call")]
struct MyCall {
addr: Address,
old_value: String,
new_value: String,
}
assert_eq!(
MyCall::abi_signature(),
"my_call(address,string,string)"
);
