Enum hdk::prelude::InitCallbackResult

pub enum InitCallbackResult {
    Pass,
    Fail(String),
    UnresolvedDependencies(UnresolvedDependencies),
}

Expand description

The result of the DNA initialization callback.

This is the aggregated result of all of the DNA’s zome initializations. If any zome fails to initialize, the DNA initialization at large will fail.

See HDK documentation on init callback.

§Examples

Passing initialization Failing initialization

Variants§

Pass

Fail(String)

Trait Implementations§

impl CallbackResult for InitCallbackResult

fn is_definitive(&self) -> bool

if a callback result is definitive we should halt any further iterations over remaining calls e.g. over sparse names or subsequent zomes typically a clear failure is definitive but success and missing dependencies are not in the case of success or missing deps, a subsequent callback could give us a definitive answer like a fail, and we don’t want to over-optimise wasm calls and miss a clear failure
