Enum cosmwasm_std::SystemResult
source · pub enum SystemResult<S> {
Ok(S),
Err(SystemError),
}
Expand description
This is the outer result type returned by a querier to the contract.
We use a custom type here instead of Rust’s Result because we want to be able to define the serialization, which is a public interface. Every language that compiles to Wasm and runs in the ComsWasm VM needs to create the same JSON representation.
Examples
Success:
let data = Binary::from(b"hello, world");
let result = SystemResult::Ok(ContractResult::Ok(data));
assert_eq!(to_vec(&result).unwrap(), br#"{"ok":{"ok":"aGVsbG8sIHdvcmxk"}}"#);
Failure:
let error = SystemError::Unknown {};
let result: SystemResult<Binary> = SystemResult::Err(error);
assert_eq!(to_vec(&result).unwrap(), br#"{"error":{"unknown":{}}}"#);
Variants§
Ok(S)
Err(SystemError)
