Enum substrate_api_client::node_metadata::EventArg

pub enum EventArg {
    Primitive(String),
    Vec(Box<EventArg>),
    Tuple(Vec<EventArg>),
}

Naive representation of event argument types, supports current set of substrate EventArg types. If and when Substrate uses type-metadata, this can be replaced.

Used to calculate the size of a instance of an event variant without having the concrete type, so the raw bytes can be extracted from the encoded Vec<EventRecord<E>> (without E defined).

Variants

Primitive(String)

Vec(Box<EventArg>)

Tuple(Vec<EventArg>)

Implementations

impl EventArg

pub fn primitives(&self) -> Vec<String>
