Enum PrivateRpc 

pub enum PrivateRpc {
    SubmitChange,
    MetadataFetch,
    DelegationTokenMutation,
}

A krabka-private controller RPC. Its api key sits at 1000 or above, so a later Kafka assignment cannot collide with it.

Variants

SubmitChange

SubmitChange, api key 1003: a node forwards a metadata change to the controller leader.

MetadataFetch

MetadataFetch, api key 1004: an observer fetches the metadata log.

DelegationTokenMutation

DelegationTokenMutation, api key 1005: a guarded forward of a delegation-token change.

Implementations

impl PrivateRpc

pub const ALL: [Self; 3]

Every private RPC, in api-key order.

pub const fn api_key(self) -> i16

The api key of this RPC.

pub const fn from_api_key(api_key: i16) -> Option<Self>

The private RPC with api_key, or None for any other key.

pub const fn max_request_version(self, krabka_version: i16) -> Option<i16>

The highest request version of this RPC that a node may send when the finalized krabka.version is krabka_version. None for a level outside [KRABKA_VERSION_MIN, KRABKA_VERSION_MAX]: no node of this build can see such a level finalized, because the controller finalizes only a level that every node supports.

Trait Implementations

impl Clone for PrivateRpc

fn clone(&self) -> PrivateRpc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PrivateRpc

impl Debug for PrivateRpc

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

Formats the value using the given formatter.

impl Eq for PrivateRpc

impl Hash for PrivateRpc

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PrivateRpc

fn cmp(&self, other: &PrivateRpc) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PrivateRpc

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for PrivateRpc

fn partial_cmp(&self, other: &PrivateRpc) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
