Struct PolicyTreeNode 

#[non_exhaustive]
pub struct PolicyTreeNode {
    pub depth: usize,
    pub valid_policy: ObjectIdentifier,
    pub expected_policy_set: Vec<ObjectIdentifier>,
    pub qualifiers: Vec<PolicyQualifierInfo>,
}

A node in the §6.1.5 valid_policy_tree, exposed for post-validation qualifier extraction on ValidatedPath::valid_policy_tree.

This is the public mirror of the internal PolicyNode type. It is intentionally a separate public type so that the internal node shape (which may evolve as the path-validator gains features) is not part of the public API surface.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

depth: usize

Depth at which this node appears in the tree.

0 is the synthetic anyPolicy root sentinel (always present while the tree is alive; carries no qualifiers). 1 is the trust-anchor-adjacent CA. n is the leaf.

valid_policy: ObjectIdentifier

The policy OID this node represents.

May be id-ce-certificatePolicies-anyPolicy (2.5.29.32.0) for nodes that survived an anyPolicy expansion or were not yet materialized into specific policies.

expected_policy_set: Vec<ObjectIdentifier>

Set of policies in the next certificate that are consistent with this node, per RFC 5280 §6.1.2(a) expected_policy_set.

Initialized to {valid_policy} and updated by PolicyMappings extensions during the walk.

qualifiers: Vec<PolicyQualifierInfo>

Policy qualifiers attached to this node, in the upstream PolicyQualifierInfo form: a (policy_qualifier_id, qualifier) pair where qualifier is a raw der::Any. Decoding is left to the caller because the x509-cert 0.2.5 UserNotice type has an upstream typo on notice_ref — pass-through avoids the buggy decoder. The two standard qualifier IDs are id-qt-cps (1.3.6.1.5.5.7.2.1, qualifier is a CPSuri / IA5String) and id-qt-unotice (1.3.6.1.5.5.7.2.2, qualifier is a UserNotice).

Trait Implementations

impl Clone for PolicyTreeNode

fn clone(&self) -> PolicyTreeNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyTreeNode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PolicyTreeNode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PolicyTreeNode

impl PartialEq for PolicyTreeNode

fn eq(&self, other: &PolicyTreeNode) -> 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 Serialize for PolicyTreeNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
