Crate holochain_zome_types
source · [−]Expand description
Holochain Zome Types: only the types needed by Holochain application developers to use in their Zome code, and nothing more.
This crate is intentionally kept as minimal as possible, since it is typically included as a dependency in Holochain Zomes, which are distributed as chunks of Wasm. In contrast, the holochain_types crate contains more types which are used by Holochain itself.
Re-exports
pub use kitsune_p2p_timestamp as timestamp;pub use prelude::*;Modules
represent arbitrary bytes (not serialized) e.g. totally random crypto bytes from random_bytes
Capability Grants and Claims
A “Cell” represents a DNA/AgentId pair - a space where one dna/agent can track its source chain and service network requests / responses.
Countersigned entries involve preflights between many agents to build a session that is part of the entry.
Re-exported dependencies
Defines DnaDef struct
An Entry is a unit of data in a Holochain Source Chain.
Fixturators for zome types
Types related to the genesis process whereby a user commits their initial
records and validates them to the best of their ability. Full validation
may not be possible if network access is required, so they perform a
“self-check” (as in “check yourself before you wreck yourself”) before
joining to ensure that they can catch any problems they can before being
subject to the scrutiny of their peers and facing possible rejection.
For more details see holochain_integrity_types::genesis.
Items related to the DNA initialization callback.
Wrapper type to indicate some data which has a ValidationStatus associated with it.
Metadata types for use in wasm
For more details see holochain_integrity_types::op.
Common types
Types for source chain queries
Types for rate limiting
Defines a Record, the basic unit of Holochain data.
Types for requesting metadata
Schedule functions to run outside a direct zome call.
App-defined signals
Signature for authenticity of data
Common helpers for writing tests against zome types
Types related to the debug host function
Tracking versions between the WASM host and guests and other interfaces.
Types for warrants
A Zome is a module of app-defined code which can be run by Holochain.
A group of Zomes are composed to form a DnaDef.
Macros
Serialization for fixed arrays is generally not available in a way that can be derived. Being able to wrap fixed size arrays is important e.g. for crypto safety etc. so this is a simple way to implement serialization so that we can send these types between the host/guest.

Cryptographic secrets are fiddly at the best of times.
Enums
Action contains variants for each type of action.
Structure holding the entry portion of a chain record.
Errors related to the secure primitive macro.
Statics
10MB of entropy free for the taking. Useful for initializing arbitrary::Unstructured data
