Struct PartitionBudget 

pub struct PartitionBudget { /* private fields */ }

The finite worker and connection budget for one M4 partition manager.

Implementations

impl PartitionBudget

pub fn new( max_partition_workers: u8, repository_pool_size: u32, ) -> Result<Self, PlanError>

Constructs validated worker-concurrency and connection bounds.

Errors

Rejects zero/over-limit concurrency or a pool that cannot supply every active worker plus the owning parent connection.

pub const fn max_partition_workers(self) -> u8

Returns the maximum concurrent partition workers.

pub const fn repository_pool_size(self) -> u32

Returns the validated repository pool size.
