Struct ResourceGroup 

pub struct ResourceGroup {
    pub name: String,
    pub max_concurrency: usize,
    pub max_queue: usize,
    pub memory_bytes: u64,
    pub temporary_disk_bytes: u64,
    pub work_units: u64,
    pub cpu_weight: u32,
    pub priority: u8,
    pub max_result_bytes: u64,
}

Bounds for one class of admitted work (spec section 10.5, S1E-002).

The field set is exactly the spec’s. priority is a u8, so the spec’s 0..=255 range is enforced by the type itself (and by serde on the cluster-settings path); validate covers the remaining invariants: non-empty name and nonzero weights.

Fields

name: String

Unique (per tenant) group name.

max_concurrency: usize

Maximum concurrently executing queries.

max_queue: usize

Maximum queued queries awaiting a concurrency slot.

memory_bytes: u64

Memory budget in bytes (enforced via the memory governor, S1E-003).

temporary_disk_bytes: u64

Temporary-disk budget in bytes (spill manager, S1E-004).

work_units: u64

Work-unit budget (weighted CPU/I/O accounting units).

cpu_weight: u32

CPU scheduling weight (relative share; must be nonzero).

priority: u8

Scheduling priority, 0..=255 (higher runs first).

max_result_bytes: u64

Maximum bytes of one query’s result.

Implementations

impl ResourceGroup

pub fn validate(&self) -> Result<(), ResourceError>

Checks the invariants not carried by the field types: non-empty name and nonzero weights (priority’s 0..=255 range is the u8 type).

pub fn for_class(class: WorkloadClass) -> Self

The configured default group for a workload class (spec §13.1 queue set). Control and replication receive generous, always-reserved capacity; foreground classes outrank analytics, which outranks maintenance and backup. Operators reconfigure these through the registry; the numbers are starting points, not policy.

Trait Implementations
