Enum ProtectionLevel 

pub enum ProtectionLevel {
    None,
    Sign,
    Encrypt,
}

Abstract protection level for the policy layer.

Unlike ProtectionKind (XML parser type, 5 variants incl. origin authentication), ProtectionLevel carries only the 3 base classes. Policy decisions compare/order these levels — the origin-auth refinement follows from PolicyDecision::suite (receiver-specific MACs, RC1).

The order None < Sign < Encrypt is relevant for the “strongest value wins” matching in stage 3 (SEDP endpoint caps) — Ord/PartialOrd are defined accordingly.

Variants

None

No protection — plaintext RTPS on the wire.

Sign

Integrity protection (HMAC/AEAD tag), payload stays readable.

Encrypt

Integrity + confidentiality (AEAD ciphertext).

Implementations

impl ProtectionLevel

pub fn from_protection_kind(kind: ProtectionKind) -> Self

Mapping from the governance-XML ProtectionKind. Origin-auth variants collapse to their base class; the origin-auth property is transported via PolicyDecision::suite + receiver-specific MAC encoding.

pub fn to_protection_kind(self) -> ProtectionKind

Reverse mapping to ProtectionKind without origin-auth refinement.

pub fn stronger(self, other: Self) -> Self

Picks the stronger of two levels (e.g. writer vs. reader offer).

Trait Implementations

impl Clone for ProtectionLevel

fn clone(&self) -> ProtectionLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtectionLevel

impl Debug for ProtectionLevel

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

Formats the value using the given formatter.

impl Default for ProtectionLevel

fn default() -> ProtectionLevel

Returns the “default value” for a type.

impl Eq for ProtectionLevel

impl Hash for ProtectionLevel

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 ProtectionLevel

fn cmp(&self, other: &ProtectionLevel) -> 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 ProtectionLevel

fn eq(&self, other: &ProtectionLevel) -> 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 ProtectionLevel

fn partial_cmp(&self, other: &ProtectionLevel) -> 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.
