Implementations

impl FileAttr

pub fn check_perm( &self, uid: u32, gid: u32, access_mode: u8, ) -> AsyncFusexResult<()>

File permissions in Unix/Linux systems are represented as a 12-bit structure, laid out as follows: ┌───────────────┬─────────┬─────────┬─────────┐ │ Special │ User │ Group │ Other │ ├───────────────┼─────────┼─────────┼─────────┤ │ 3 Bits │ 3 Bits │ 3 Bits │ 3 Bits │ ├───────────────┼─────────┼─────────┼─────────┤ │ suid|sgid|stky│ r w x │ r w x │ r w x │ └──────┬───────┴────┬────┴────┬────┴────┬────┘ │ │ │ │ │ │ │ └─ Other: Read, Write, Execute permissions for other users. │ │ └─ Group: Read, Write, Execute permissions for group members. │ └─ User: Read, Write, Execute permissions for the owner of the file. └─ Special: Set User ID (suid), Set Group ID (sgid), and Sticky Bit (stky). When Sticky Bit set on a directory, files in that directory may only be unlinked or - renamed by root or the directory owner or the file owner.
