Struct Node 

pub struct Node<T: Element> { /* private fields */ }

A node in a quorum system.

Nodes are identified by x: equality, ordering, and hashing only look at x. Capacities are in requests per unit time; the defaults are a capacity of 1.0 and a latency of 1 second.

Implementations

impl<T: Element> Node<T>

pub fn new(x: T) -> Self

Create a node with capacity 1.0 and latency 1 second.

pub fn with_capacity(self, capacity: f64) -> Result<Self>

Set one capacity for both reads and writes.

Errors

Returns Error::InvalidExpression unless capacity is finite and positive.

pub fn with_read_write_capacity(self, read: f64, write: f64) -> Result<Self>

Set separate read and write capacities.

Errors

Returns Error::InvalidExpression unless both capacities are finite and positive.

pub fn with_latency(self, latency: Duration) -> Self

Set the latency for this node.

pub fn x(&self) -> &T

The node identifier.

pub fn read_capacity(&self) -> f64

Read capacity (requests per unit time).

pub fn write_capacity(&self) -> f64

Write capacity (requests per unit time).

pub fn latency(&self) -> Duration

Latency of a request to this node.
