The bits.

These are accepted by operations such as Luv.File.chmod in lists, e.g.

[`IRUSR; `IWUSR; `IRGRP; `IROTH]

The special constructor `NUMERIC can be used to specify bits directly in octal. The above list is equivalent to:

[`NUMERIC 0o644]

`IFREG is available since Luv 0.5.5.

`IFMT, `IFDIR, `IFBLK, `IFCHR, `IFLNK, `IFIFO are available since Luv 0.5.4.

type numeric

Abstract type for a bit field of permissions bits, i.e., an int in which multiple bits may be set. These bit fields are returned by operations such as Luv.File.stat.

val test : t list -> numeric -> bool

Luv.File.Mode.test mask bits checks whether all the bits in mask are set in bits. For example, if bits contains 0o644, Luv.File.Mode.test [`IRUSR] bits evaluates to true.
