Struct concordium_std::Action

#[must_use]
pub struct Action { /* fields omitted */ }

Actions that can be produced at the end of a contract execution. This type is deliberately not cloneable so that we can enforce that and_then and or_else can only be used when more than one event is created.

This type is marked as must_use since functions that produce values of the type are effectful.

Implementations

impl Action

pub fn tag(&self) -> u32
