func MustLoad ¶

func MustLoad[T any]() T

MustLoad loads environment variables into a struct of type T based on struct tags. It panics if any required variable is missing and has no default.

Supported struct tags:

env:"VAR_NAME"       — the environment variable to read
default:"value"      — fallback value when the env var is empty
required:"true"      — panic if missing and no default (this is the default behavior)
required:"false"     — leave the zero value if missing and no default

Supported field types: string, int, int64, float64, bool, time.Duration, []string.
