Types ¶

type Data ¶

type Data struct {
	Data []byte
	// contains filtered or unexported fields
}

Data is mmap'ed read-only data from a file. The backing file is never closed, so Data remains valid for the lifetime of the process.

func Mmap ¶

func Mmap(file string) (Data, bool, error)

Mmap maps the given file into memory. The boolean result indicates whether the file was opened. If it is true, the caller should avoid attempting to write to the file on Windows, because Windows locks the open file, and writes to it will fail.
