Struct TrustPolicy 

pub struct TrustPolicy { /* private fields */ }

Local trust roots and cryptographically signed delegations.

Implementations

impl TrustPolicy

pub fn new() -> Self

Create an empty local policy.

pub fn with_root(signing_key: &SigningKey) -> Self

Create a policy with one trusted root.

pub fn trust_author(&mut self, author: &VerifyingKey)

Trust an author directly as a local root.

pub fn revoke_author(&mut self, author: &VerifyingKey)

Revoke a local trust root or delegate identity.

pub fn add_delegation(&mut self, delegation: TrustDelegation) -> Result<bool>

Add a signed delegation issued by an already trusted author.

Errors

Returns an error if the delegation is invalid, expired, or not issued by an identity trusted for its scope.

pub fn revoke_delegation( &mut self, delegator: &str, delegate: &str, scope: Option<&Hash>, ) -> Result<bool>

Revoke an active delegation matching the delegate, scope, and delegator.

Returns true if any delegation was marked revoked.

Errors

This method does not return errors.

pub fn revoke_delegation_at( &mut self, delegator: &str, delegate: &str, scope: Option<&Hash>, at: u64, ) -> Result<bool>

Revoke a delegation using an explicit revocation time.

Returns true if any delegation was marked revoked.

Errors

This method does not return errors.

pub fn add_delegation_at( &mut self, delegation: TrustDelegation, now: u64, ) -> Result<bool>

Add a signed delegation using an explicit validation time.

Errors

Returns an error if the delegation is invalid, expired, or not issued by an identity trusted for its scope.

pub fn evaluate(&self, author: &str) -> TrustDecision

Return the local trust decision for an author.

pub fn evaluate_at(&self, author: &str, now: u64) -> TrustDecision

Return the local trust decision at an explicit time.

pub fn evaluate_for( &self, author: &str, content: Option<&Hash>, ) -> TrustDecision

Return the local trust decision for an author and optional content.

pub fn evaluate_for_at( &self, author: &str, content: Option<&Hash>, now: u64, ) -> TrustDecision

Return the local trust decision for an author and content at an explicit time.

pub fn is_trusted_for(&self, author: &str, content: Option<&Hash>) -> bool

Return whether an author is trusted for the requested content.

pub fn is_trusted_for_at( &self, author: &str, content: Option<&Hash>, now: u64, ) -> bool

Return whether an author is trusted at an explicit time.

impl Clone for TrustPolicy

fn clone(&self) -> TrustPolicy

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

Performs copy-assignment from source.

impl Debug for TrustPolicy

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

impl Default for TrustPolicy

fn default() -> TrustPolicy
