pub(super) fn caller_block(
regs: &[AgentRegistration],
uid: Option<&str>,
block: Option<&str>,
agent: Option<&str>,
) -> Option<String>Expand description
The caller’s own block: by its token’s UID, else the block id it sent, else its name when exactly one registered agent has it. Only used to leave the caller out and to read its own repository, so a name is enough.
