Struct re_query::PromiseResolver

source · 
pub struct PromiseResolver {}
Expand description

Resolves and keeps track of Promises.

Implementations§

source§

impl PromiseResolver

source

pub fn resolve(&self, promise: &Promise) -> PromiseResult<DataCell>

Resolves the given Promise.

If the method returns PromiseResult::Pending, you should call it again with the same Promise until it either resolves it or fails irrecoverably.

Once a Promise has left the Pending state, resolveing it again is cached and idempotent (the PromiseResolver keeps track of the state of all Promises, both pending and already resolved).
