Struct Access 

pub struct Access {
    pub mode: u32,
    pub user: u32,
    pub group: u32,
    pub control: [u8; 32],
}

Who may use a file or directory, as publishing keeps it: where there are no modes, a read-only file has none of the write bits.

On Unix: the permission bits, the owner and the group, and on Linux the mandatory access control labels (SELinux, Smack), which publishing requires to be the same on every entry it compares. Access control that publishing could not keep is refused when the access is read: on Linux an access control list. On macOS and Windows access control lists are neither read nor kept.

Fields

mode: u32

The permission bits, with the set-user, set-group and sticky bits.

user: u32

The owning user.

group: u32

The owning group.

control: [u8; 32]

A digest of the mandatory access control labels (Linux), all zero where there are none.

Implementations

impl Access

pub const fn group_reads_alone(&self) -> bool

Whether the group may read and others may not, so that the group says who may.

pub const fn nested(&self, directory: bool) -> bool

Whether the classes that may reach content through an entry with this access, a directory if directory, nest: its owner may whenever its group may, and its group whenever others may. Where they do not, as for mode 0604, which denies the group what it lets others read, who may reach depends on who the owner and group are, which audience does not say.

pub fn audience(&self, directory: bool) -> Audience

Who may reach content through an entry with this access, a directory if directory.

pub fn new_file(&self) -> Self

The access a new file in a directory with this access is given: the directory’s mode without the execute bits, its group and its labels, and as its owner the user that makes it, this process’s effective user (0 where there are no users).
