InstructionPolicy

Struct InstructionPolicy 

Source
pub struct InstructionPolicy<const N: usize> { /* private fields */ }
Expand description

Instruction policy – maps capabilities to validation requirements.

Const-constructible, stack-allocated. At most N rules.

Implementations§

Source§

impl<const N: usize> InstructionPolicy<N>

Source

pub const fn new() -> Self

Create an empty policy.

Source

pub const fn when(self, cap: Capability, req: PolicyRequirement) -> Self

Add a policy rule: when cap is declared, req must be satisfied.

Source

pub const fn resolve(&self, caps: &CapabilitySet) -> RequirementSet

Resolve which requirements are needed for a given capability set.

Returns the union of all requirements triggered by the declared capabilities.

Source

pub const fn rule_count(&self) -> usize

Number of rules in this policy.
