Struct ReadPolicy 

pub struct ReadPolicy {
    pub trust: TrustLevel,
    pub capabilities: CapabilitySet,
}

The trust level and capability set governing a read.

Pairs a TrustLevel with a CapabilitySet so the kernel can both check possession and apply trust-sensitive policy.

Fields

trust: TrustLevel

The trust level of the source being read.

capabilities: CapabilitySet

The capabilities granted to the read.

Implementations

impl ReadPolicy

pub fn require(&self, capability: &CapabilityName) -> Result<()>

Demands a capability, applying trust policy on top of possession.

Returns Error::CapabilityDenied when the capability is not granted, and Error::TrustDenied when an Untrusted source requests the read-eval capability.

Trait Implementations

impl Clone for ReadPolicy

fn clone(&self) -> ReadPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadPolicy

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

Formats the value using the given formatter.

impl Default for ReadPolicy

fn default() -> ReadPolicy

Returns the “default value” for a type.

impl Eq for ReadPolicy

impl PartialEq for ReadPolicy

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