Enum AuthorityTier 

pub enum AuthorityTier {
    Derived,
    Candidate,
    Agent,
    User,
}

Trust-tier ranking used to fold an authority label across N sources.

The compressor cannot launder authority upward: the produced summary’s authority tier equals the LOWEST tier among the sources. The string representation written to the durable row is the lowest source’s authority string verbatim — that is, if all sources are "candidate" then the produced summary is "candidate", even if the trust rank would notionally permit a higher label.

Variants

Derived

Derived, tool, runtime, external, missing, or failed-verify source. Lowest trust.

Candidate

Candidate-tier memory (not yet accepted).

Agent

Verified agent-authored source.

User

Verified user / manual-correction source. Highest trust.

Implementations

impl AuthorityTier

pub const fn trust_rank(self) -> u8

Integer trust rank: lower is less trusted.

pub fn parse_lenient(authority: &str) -> Self

Best-effort parse of a stored authority string into a tier rank. Unknown values are conservatively classified as the lowest tier (AuthorityTier::Derived) so an unfamiliar label cannot accidentally launder a compression upward.

Trait Implementations

impl Clone for AuthorityTier

fn clone(&self) -> AuthorityTier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthorityTier

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

Formats the value using the given formatter.

impl Ord for AuthorityTier

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

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

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