Struct zookeeper::Acl

pub struct Acl {
    pub perms: Permission,
    pub scheme: String,
    pub id: String,
}

An access control list.

In general, the ACL system is similar to UNIX file access permissions, where znodes act as files. Unlike UNIX, each znode can have any number of ACLs to correspond with the potentially limitless (and pluggable) authentication schemes. A more surprising difference is that ACLs are not recursive: If /path is only readable by a single user, but /path/sub is world-readable, then anyone will be able to read /path/sub.

See the ZooKeeper Programmer’s Guide for more information.

Fields

perms: Permission

The permissions associated with this ACL.

scheme: String

The authentication scheme this list is used for. The most common scheme is "auth", which allows any authenticated user to do anything (see creator_all).

id: String

The ID of the user under the scheme. For example, with the "ip" scheme, this is an IP address or CIDR netmask.

Implementations

impl Acl

pub fn new<T, U>(permissions: Permission, scheme: T, id: U) -> Aclwhere
    T: ToString,
    U: ToString,

Create a new ACL with the given permissions, scheme, and id.

pub fn creator_all() -> &'static Vec<Acl>

This ACL gives the creators authentication id’s all permissions.

pub fn open_unsafe() -> &'static Vec<Acl>

This is a completely open ACL.

pub fn read_unsafe() -> &'static Vec<Acl>

This ACL gives the world the ability to read.

Trait Implementations

impl Clone for Acl

fn clone(&self) -> Acl

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Acl

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Acl

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<Acl> for Acl

fn eq(&self, other: &Acl) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
