Fields

version: u8

Schema version for this locator type.

pool: String

Pool name.

topic: String

Topic name.

num_partitions: u32

Number of partitions.

partition_stride: u32

Partition stride (slot size in bytes).

partition_capacity: u32

Partition capacity (number of slots per partition).

partition_lease_ids: Vec<u128>

Lease IDs for each partition’s backing memory.

Implementations

impl TopicLocator

pub fn new( pool: &str, topic: &str, num_partitions: u32, partition_stride: u32, partition_capacity: u32, ) -> Self

Create a new v1 topic locator.

pub fn with_lease_ids(self, ids: Vec<u128>) -> Self

Set the lease IDs for each partition.

Trait Implementations

impl Clone for TopicLocator

fn clone(&self) -> TopicLocator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicLocator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TopicLocator

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TopicLocator

fn eq(&self, other: &TopicLocator) -> 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 Serialize for TopicLocator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
