Struct ScoreDescending 

pub struct ScoreDescending;

Rank the whole mixed set by raw score, descending — the reference host’s documented default (SPEC.md §6.6), and what super::order_by_value has always done.

It is a real policy with a real cost: the provider that scores most generously wins the top of the prompt and the front of the budget, whatever its evidence is worth. It stays the default because it is the only strategy here that changes nothing for a host that never asked for a ranking policy, and because with a single provider it is simply the right answer — see ADR 0015.

Trait Implementations

impl Clone for ScoreDescending

fn clone(&self) -> ScoreDescending

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScoreDescending

impl Debug for ScoreDescending

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

Formats the value using the given formatter.

impl Default for ScoreDescending

fn default() -> ScoreDescending

Returns the “default value” for a type.

impl Eq for ScoreDescending

impl PartialEq for ScoreDescending

fn eq(&self, other: &ScoreDescending) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RankingStrategy for ScoreDescending

fn policy_name(&self) -> &str

The policy’s name, for a host that has to state which cross-provider ordering it applied. F10 requires a host to document the choice; a strategy that cannot say what it is makes that impossible, which is why this has no default implementation.

fn order(&self, frames: &[(String, ContextFrame)]) -> Vec<usize>

Order the input indices best-first. See the trait contract.
