Struct ApplyHwConfigurationParams 

pub struct ApplyHwConfigurationParams<'a> {
    pub mode: HwClusterMode,
    pub target_group_name: &'a str,
    pub parent_group_name: &'a str,
    pub pattern: &'a str,
    pub dryrun: bool,
    pub create_target_group: bool,
    pub delete_empty_parent_group: bool,
}

Pin or unpin nodes between parent_group_name and target_group_name so the target group satisfies pattern.

The flow is parse → ensure → score → resolve → apply: the component pattern is parsed into a counts map, the target group is created on demand (or refused when create_target_group is false and the group is missing), parent and target hardware inventories are fetched, the resource-sufficiency check rejects patterns that ask for more of a component than exists in the pool, and mode (Pin / Unpin) picks which selection algorithm runs. dryrun shortcuts every backend mutation but still returns the would-be final memberships so the operator sees the plan. Parameters for apply_hw_configuration.

Fields

mode: HwClusterMode

Pin (capacity-aware selection) or Unpin (release all).

target_group_name: &'a str

Destination HSM group that will receive nodes matching pattern.

parent_group_name: &'a str

Source HSM group nodes are drawn from when honouring pattern.

pattern: &'a str

Hardware-component request string, e.g. "a100:8,milan:2".

dryrun: bool

When true, plan the moves but skip every backend mutation; the returned ApplyHwResult still reflects the would-be membership.

create_target_group: bool

Create target_group_name if it doesn’t already exist.

delete_empty_parent_group: bool

Delete the parent group when the move leaves it with no members.
