Struct concordium_std::ParseError [−][src]
pub struct ParseError {}Expand description
Zero-sized type to represent an error when reading bytes and deserializing.
When using custom error types in your smart contract, it is convenient to
implement the trait From<ParseError> for you custom error type, to allow
using the ? operator when deserializing bytes, such as the contract state
or parameters.
