Functions

func LimitReader

func LimitReader(r io.Reader, n uint64) (limited io.Reader)

LimitReader returns an io.Reader that reads up to n bytes. Once that limit is reached, [ErrLimit] is returned from limited.Read. limited.Read is not safe for concurrent use. n must be non-negative.

Types

type LimitError

type LimitError struct {
	// Limit is the limit that triggered the error.
	Limit uint64
}

LimitError is returned when the Limit is reached.

func (*LimitError) Error

func (err *LimitError) Error() (msg string)

Error implements the error interface for *LimitError.
