Struct FsPermission

pub struct FsPermission { /* private fields */ }

Implementations

impl FsPermission

pub fn update_short(&mut self, n: i16)

pub fn to_short(&self) -> i16

Encode the object to a short.

pub fn apply_umask(&self, umask: &FsPermission) -> Self

Apply a umask to this permission and return a new one.

The umask is used by create, mkdir, and other Hadoop filesystem operations. The mode argument for these operations is modified by removing the bits which are set in the umask. Thus, the umask limits the permissions which newly created files and directories get.

pub fn get_umask(conf: Option<&Configuration>) -> Result<Self>

Get the user file creation mask (umask)

[UMASK_LABEL] config param has umask value that is either symbolic or octal.

Symbolic umask is applied relative to file mode creation mask; the permission op characters ‘+’ clears the corresponding bit in the mask, ‘-’ sets bits in the mask.

Octal umask, the specified bits are set in the file mode creation mask.

pub fn get_dir_default() -> Self

Get the default permission for directory.

pub fn get_file_default() -> Self

Get the default permission for file.
