# README

Gouuid GitHub license

A golang utility to work with uuid types.

Installation

go get github.com/ubgo/gouuid

DefaultIfEmpty(val *uuid.UUID) uuid.UUID

FuncName will return the current function's name. Check if pointer of uuid is empty then return the default 00000000-0000-0000-0000-000000000000

gouuid.DefaultIfEmpty(nil) // output: 00000000-0000-0000-0000-000000000000

uid := uuid.New()
gouuid.DefaultIfEmpty(&uid) // output: some uid b7729c88-47e9-42a7-92d3-3e6bcc585f73

ParseToDefault(val string) uuid.UUID

Parse string as uuid and return default if error

ParseToDefault("not_uid") // output: 00000000-0000-0000-0000-000000000000

uid := uuid.New().String()
result = ParseToDefault(uid) // output: some uid b7729c88-47e9-42a7-92d3-3e6bcc585f73

IndexOf(slice []uuid.UUID, val uuid.UUID) (int, bool)

Check if value exist on a given uuid slice then return the index

ids := []uuid.UUID{ParseToDefault("b7729c88-47e9-42a7-92d3-3e6bcc585f73"), ParseToDefault("83adb35a-847a-4962-8e09-8311a45dc2a2"), ParseToDefault("d9d65dfc-4643-44ab-920f-c564259fd96c")}
result, _ := IndexOf(ids, ParseToDefault("83adb35a-847a-4962-8e09-8311a45dc2a2"))
// output: 1, true

# Functions

Check if pointer of uuid is empty then return the default 00000000-0000-0000-0000-000000000000 Use Case: let say we have ImageID : UUID sent by user via Rest API empty (nil) but database is required soem value So we need to validate the nil value before sending it to the database insert query.
Extract Slice of []uuid.UUID from a given any slice of struct.
Find the index of UUID in a give Slice.
Convert custom types to uuid.UUID[] e.g.
Try to parse string as uuid and return default if error.
Convert Postgres array `{c4ba81a1-9e57-4e60-b811-2860136ab803,e0d6cbbb-e5b8-4f84-9f11-65b7e14e5817}` to UUID Slide uuid.UUID[].
Convert slide of UUIDs to String Slice.
