Enum holochain_types::prelude::Action

Action contains variants for each type of action.

This struct really defines a local source chain, in the sense that it implements the pointers between hashes that a hash chain relies on, which are then used to check the integrity of data using cryptographic hash functions.

Variants

AgentValidationPkg(AgentValidationPkg)

InitZomesComplete(InitZomesComplete)

CreateLink(CreateLink<RateWeight>)

DeleteLink(DeleteLink)
