Struct ContractEventDef 

#[repr(C)]
pub struct ContractEventDef {
    pub name: ContractSpecId,
    pub signature: Topic,
    pub topics: VecM<ContractField>,
    pub fields: VecM<ContractField>,
}

Describes an event emitted via the LogEvent syscall (see event.x). Topic 0 is always the event signature: sha256(MAJOR_VERSION :: CRATE_NAME :: TYPE_NAME) Topic fields and payload fields are listed separately, each in declaration order. Topic values that are not already 32 bytes wide are XDR-encoded and sha256-hashed; payload fields are XDR-encoded in order to form the event data.

Fields

name: ContractSpecId

signature: Topic

topics: VecM<ContractField>

fields: VecM<ContractField>
