Function unixSet [src]

Sets the permissions for the chosen class. Any permissions set to null are left unchanged. This method DOES NOT set permissions on the filesystem: use File.setPermissions(permissions)

Prototype

 pub fn unixSet(self: *Self, class: Class, permissions: struct { read: ?bool = null, write: ?bool = null, execute: ?bool = null, }) void

Parameters

self: *Selfclass: Class

permissions: struct {
    read: ?bool = null,
    write: ?bool = null,
    execute: ?bool = null,
}

Source

  pub fn unixSet(self: *Self, class: Class, permissions: struct {
    read: ?bool = null,
    write: ?bool = null,
    execute: ?bool = null,
}) void {
    const shift = @as(u3, @intFromEnum(class)) * 3;
    if (permissions.read) |r| {
        if (r) {
            self.mode |= @as(Mode, 0o4) << shift;
        } else {
            self.mode &= ~(@as(Mode, 0o4) << shift);
        }
    }
    if (permissions.write) |w| {
        if (w) {
            self.mode |= @as(Mode, 0o2) << shift;
        } else {
            self.mode &= ~(@as(Mode, 0o2) << shift);
        }
    }
    if (permissions.execute) |x| {
        if (x) {
            self.mode |= @as(Mode, 0o1) << shift;
        } else {
            self.mode &= ~(@as(Mode, 0o1) << shift);
