Struct Cap 

pub struct Cap {
    pub target: CapTarget,
    pub rights: CapRights,
    pub native_mask: Option<NativeMask>,
    /* private fields */
}

Authorization record stored in the runtime Cap table, never in bytecode.

Fields

target: CapTarget

rights: CapRights

native_mask: Option<NativeMask>

Meaningful only when rights.contains(NATIVE).

Implementations

impl Cap

pub fn root( target: CapTarget, rights: CapRights, native_mask: Option<NativeMask>, cell: &RevocationCell, ) -> Self

Trusted root mint (runtime / host only). Bytecode cannot call this.

pub fn epoch(&self) -> u64

pub fn is_valid(&self, cell: &RevocationCell) -> bool

pub fn attenuate( &self, want_rights: CapRights, want_native: Option<&NativeMask>, ) -> Cap

Produce a strictly narrower-or-equal Cap. Never panics, never grants a bit the parent did not have. This is the single choke point the rest of the model sits on — keep it boring and obvious.
