Golang collections for builtin types and generic slices

collections-go

Mutable and immutable collections for commonly used builtin types. This package includes collection types generated by collections-gen for the following builtins:

• byte (collections.Byte, collections.ImmutableByte)
• []byte (collections.ByteSlice, collections.ImmutableByteSlice)
• float32 (collections.Float32, collections.ImmutableFloat32)
• float64 (collections.Float64, collections.ImmutableFloat64)
• int (collections.Int, collections.ImmutableInt)
• int64 (collections.Int64, collections.ImmutableInt64)
• int32 (collections.Int32, collections.ImmutableInt32)
• string (collections.String, collections.ImmutableString)

In addition to that the following hand crafted collection types are included:

• generic collections based on interface{} types and the reflect package (collections.Generic, collections.ImmutableGeneric)

Installation

go get github.com/martinohmann/collections-go

Usage

c := collections.NewString([]string{"foo", "bar", "baz"})

items := c.
    Filter(func(item string) bool {
        return strings.HasPrefix(item, "ba")
    }).
    Reverse().
    Prepend("qux").
    Items()

fmt.Println(items)

// Output:
// [qux baz bar]
