Enum ScoringPolicy 

#[non_exhaustive]
pub enum ScoringPolicy {
    SameBinary,
    Stable,
}

Policy for ranking candidates returned by rank_candidates.

The two policies differ in whether binary identity or path stability is the primary criterion. See rank_candidates for usage.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SameBinary

Prefer the candidate that points to the same binary as the input (by canonical path or content), then break ties by path stability.

This is the default and is appropriate for service registration, where the exact same binary file must be referenced.

Stable

Prefer the candidate with the most stable path, then break ties by binary identity.

Useful for configuration files that should survive binary upgrades (the path keeps working even if the underlying file changes).

Trait Implementations

impl Clone for ScoringPolicy

fn clone(&self) -> ScoringPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScoringPolicy

impl Debug for ScoringPolicy

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

Formats the value using the given formatter.

impl Default for ScoringPolicy

fn default() -> ScoringPolicy

Returns the “default value” for a type.

impl Eq for ScoringPolicy

impl PartialEq for ScoringPolicy

fn eq(&self, other: &ScoringPolicy) -> 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.
