Struct CapId 

pub struct CapId(/* private fields */);

Unpredictable capability token. Never a flow id.

0 is reserved as CapId::NONE (“no grant”, e.g. host hops without a reply address). Minted ids are never zero.

Implementations

impl CapId

pub const NONE: CapId

Placeholder used on unauthenticated / host-injected hops.

pub fn random() -> Result<Self, CapIdError>

Draw a non-zero id from the OS CSPRNG. Never panics.

pub const fn is_none(self) -> bool

pub const fn as_u128(self) -> u128
