Enum KernelImage 

pub enum KernelImage {
    GasMeter,
    StorageQuota,
    Gas,
    Quota,
    YieldSender,
    YieldReceiver,
    File,
    HostOpen,
    HostSave,
}

Identifies which kernel-assisted Image a given image_hash_chain refers to.

The four kernel-assisted Instance variants of the v3 design are Gas{meter_key}, Quota{quota_key}, YieldSender{yield_key} (the EMIT right) and YieldReceiver{Vec<yield_key>} (the CATCH right), plus the two kernel-internal tables (GasMeter, StorageQuota) the unit handles index. The older per-syscall factory/marker images (set_gas_meter, mint_gas, yield_catcher, oog_marker, …) are gone: a syscall is now a host_yield of a YieldSender carrying a kernel:* yield_key, caught by the kernel as the root YieldReceiver — so those names are yield_keys, not Images.

Variants

GasMeter

Kernel-internal gas meter table (never in chain hands).

StorageQuota

Kernel-internal storage quota table (never in chain hands).

Gas

Per-Instance Gas{meter_key} unit handle. State: a meter_key: Key packed into the handle’s registers (see crate::slot::key_to_regs).

Quota

Per-Instance Quota{quota_key} unit handle.

YieldSender

YieldSender{yield_key} — the EMIT right for a yield_key. State: the yield_key: Key packed into the handle’s registers.

YieldReceiver

YieldReceiver{Vec<yield_key>} — the CATCH right: the set of yield_keys an Instance catches. State (a serialized Set<Key>) lives in the handle’s mem DataCap; the kernel short-circuits it during routing.

File

Per-Instance File{file_id} handle.

HostOpen

Per-Instance HostOpen handle.

HostSave

Per-Instance HostSave handle.

Trait Implementations

impl Clone for KernelImage

fn clone(&self) -> KernelImage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KernelImage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for KernelImage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KernelImage

fn eq(&self, other: &KernelImage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
