Enum CapToken 

#[non_exhaustive]
pub enum CapToken {
    StateRead,
    StateWrite,
    EmitExtraBytes,
    FuelConsumed,
}

Capability tokens an enabled hook may request from the host. Each token grants permission to call a single host-side function — non- whitelisted imports are rejected at module-load (E14.L2-Allow enforcement).

#[non_exhaustive] — additive expansion is non-breaking (TypeCode forward-compat). Ord/PartialOrd are required so CapToken can live in a deterministic std::collections::BTreeSet (the HookStoreData::capabilities container — deterministic iteration matters for the call-time capability check audit log).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StateRead

arkhe:hook/state.read — read the hook-scoped key/value scratchpad.

StateWrite

arkhe:hook/state.write — write the hook-scoped scratchpad.

EmitExtraBytes

arkhe:hook/emit.extra_bytes — append into ExtraBytesBuilder.

FuelConsumed

arkhe:hook/fuel.consumed — query remaining fuel budget.

Trait Implementations

impl Clone for CapToken

fn clone(&self) -> CapToken

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapToken

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

Formats the value using the given formatter.

impl Hash for CapToken

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 Ord for CapToken

fn cmp(&self, other: &CapToken) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CapToken

fn eq(&self, other: &CapToken) -> 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.

impl PartialOrd for CapToken

fn partial_cmp(&self, other: &CapToken) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
