pair

pair

Combine parallel slices without index math.

Slices must be equal length — these are parallel data, not ragged collections. X[V1, V2] holds two values, accessed via .V1 and .V2.

pairs := pair.Zip(names, scores)  // []X[string, int]

What It Looks Like

// Zip and iterate
for _, p := range pair.Zip(names, ages) {
    fmt.Printf("%s is %d\n", p.V1, p.V2)
}

// Transform while zipping
users := pair.ZipWith(names, ages, NewUser)

Operations

• Of[V1, V2](V1, V2) X[V1, V2] — create a pair
• Zip[V1, V2]([]V1, []V2) []X[V1, V2] — combine slices into pairs
• ZipWith[A, B, R]([]A, []B, func(A, B) R) []R — combine and transform

Zip and ZipWith panic if slice lengths differ.

See pkg.go.dev for complete API documentation, the main README for installation, and slice.Unzip for the inverse operation.
