var (
	// ErrNone reports that no tier matched any candidate.
	ErrNone = errors.New("no match")
	// ErrAmbiguous reports that the deciding tier matched more than one candidate.
	ErrAmbiguous = errors.New("ambiguous")
)

Functions ¶

func One ¶

func One[T any](items []T, arg string, tiers ...Tier[T]) (T, []T, error)

One tries each tier in order, and the first tier matching any candidate decides: one match is returned, more than one returns those candidates with ErrAmbiguous, and a later tier is never consulted to break the tie. ErrNone means no tier matched.

Types ¶

type Tier ¶

type Tier[T any] func(item T, arg string) bool

Tier reports whether a candidate is identified by arg under one identifier.

func Exact ¶

func Exact[T any](key func(T) string) Tier[T]

Exact matches when key(item) equals arg byte for byte. An empty key never matches.

func Fold ¶

func Fold[T any](key func(T) string) Tier[T]

Fold matches when key(item) equals arg under Unicode case folding. An empty key never matches.
