Struct ethers_contract::BaseContract
source · pub struct BaseContract {
pub methods: HashMap<Selector, (String, usize)>,
/* private fields */
}
Expand description
A reduced form of Contract
which just takes the abi
and produces
ABI encoded data for its functions.
Fields§
§methods: HashMap<Selector, (String, usize)>
A mapping from method signature to a name-index pair for accessing functions in the contract ABI. This is used to avoid allocation when searching for matching functions by signature.
Implementations§
source§impl BaseContract
impl BaseContract
sourcepub fn encode<T: Tokenize>(
&self,
name: &str,
args: T
) -> Result<Bytes, AbiError>
pub fn encode<T: Tokenize>( &self, name: &str, args: T ) -> Result<Bytes, AbiError>
Returns the ABI encoded data for the provided function and arguments
If the function exists multiple times and you want to use one of the overloaded
versions, consider using encode_with_selector
sourcepub fn encode_with_selector<T: Tokenize>(
&self,
signature: Selector,
args: T

pub fn decode<D: Detokenize, T: AsRef<[u8]>>( &self, name: &str, bytes: T ) -> Result<D, AbiError>
