go-typemeta

stores per-runtime-type metadata in a concurrency-safe manner optimized for minimum memory overhead (e.g. not hashmaps all over the place!)

Types

type Meta

type Meta atomic.Pointer[meta]

Meta is a concurrency safe singly-linked list holding key-value pairs, optimized for safety and low memory usage. Under the hood it acts similarly to how standard library context values are stored. You should not regularly rely on fetching / setting values in this, instead caching values yourself.

func Generic

func Generic[T any]() *Meta

Generic fetches Meta for generic type.

func Load

func Load(rt reflect.Type) *Meta

Load fetches Meta for reflected type.

func Of

func Of(a any) *Meta

Of fetches Meta for given type.

func (*Meta) Get

func (m *Meta) Get(key any) any

Get fetches value stored under key.

func (*Meta) Set

func (m *Meta) Set(key any, value any)

Set stores given value under key.
