Enum holochain_zome_types::capability::CapGrant
source · [−]pub enum CapGrant {
ChainAuthor(AgentPubKey),
RemoteAgent(ZomeCallCapGrant),
}
Expand description
Represents a potentially valid access grant to a zome call. Zome call response will be Unauthorized without a valid grant.
The CapGrant is not always a dedicated entry in the chain. Notably AgentPubKey entries in the current chain act like root access to local zome calls.
A CapGrant
is valid if it matches the function, agent and secret for a given zome call.
See .is_valid()
Variants
ChainAuthor(AgentPubKey)
Grants the capability of calling every extern to the calling agent, provided the calling
agent is the local chain author.
This grant is compared to the current Entry::Agent
entry on the source chain.
RemoteAgent(ZomeCallCapGrant)
Any agent other than the chain author is attempting to call an extern. The pubkey of the calling agent is secured by the cryptographic handshake at the network layer and the caller must provide a secret that we check for in a private entry in the local chain.
Implementations
sourceimpl CapGrant
impl CapGrant
sourcepub fn is_valid(
&self,
check_function: &GrantedFunction,
check_agent: &AgentPubKey,
check_secret: Option<&CapSecret>
) -> bool
pub fn is_valid(
&self,
check_function: &GrantedFunction,
check_agent: &AgentPubKey,
check_secret: Option<&CapSecret>
) -> bool
Given a grant, is it valid in isolation? In a world of CRUD, some new entry might update or delete an existing one, but we can check if a grant is valid in a standalone way.
