Functions

func Bracket

func Bracket[
	GA,
	GB,
	GANY,

	EB,

	A, B, ANY any](

	ofeb func(EB) GB,

	chainab func(GA, func(A) GB) GB,
	chainebb func(GB, func(EB) GB) GB,
	chainany func(GANY, func(ANY) GB) GB,

	acquire GA,
	use func(A) GB,
	release func(A, EB) GANY,
) GB

Bracket makes sure that a resource is cleaned up in the event of an error. The release action is called regardless of whether the body action returns and error or not.

func MakeReader

func MakeReader(ctx context.Context, rdr io.Reader) io.Reader

MakeReader creates a context aware reader

func ReadAll

func ReadAll(ctx context.Context, rdr io.Reader) E.Either[error, []byte]

ReadAll reads the content of a reader and allows it to be canceled

func WithResource

func WithResource[
	GA,
	GR,
	GANY,
	E, R, A, ANY any](
	mchain func(GR, func(R) GA) GA,
	mfold1 func(GA, func(E) GA, func(A) GA) GA,
	mfold2 func(GANY, func(E) GA, func(ANY) GA) GA,
	mmap func(GANY, func(ANY) A) GA,
	left func(E) GA,
) func(onCreate func() GR, onRelease func(R) GANY) func(func(R) GA) GA

WithResource constructs a function that creates a resource, then operates on it and then releases the resource
