Struct Shard 

pub struct Shard { /* private fields */ }

Share of a plan’s runs, the runs whose id leaves remainder index when divided by count.

Written INDEX/COUNT, as in 0/4.

Implementations

impl Shard

pub const WHOLE: Self

Every run of a plan.

pub fn new(index: u64, count: u64) -> Result<Self, ShardError>

Returns shard index of count.

Errors

Returns ShardError for a count of 0, or an index not below count.

pub fn index(self) -> u64

Remainder the shard’s run ids leave when divided by Self::count.

pub fn count(self) -> u64

Number of shards the plan is split into.

pub fn contains(self, run_id: u64) -> bool

Returns whether run run_id falls in the shard.

pub fn run_count(self, plan_runs: u64) -> u64

Returns the number of runs in the shard for a plan of plan_runs runs.
