Module queue 

Torrent queue + auto-management (active/seeding caps, FIFO position). Queue position arithmetic for auto-managed torrents.

Structs

QueueCandidate

Snapshot of a torrent for queue evaluation.

QueueConfig

Named configuration for queue evaluation limits.

QueueDecision

Result of queue evaluation: which torrents to start and stop.

QueueEntry

Compact representation of a queued torrent for position operations.

Enums

QueueCategory

Classification of a torrent for queue evaluation.

Functions

apply_preemption

Post-pass: for each category, if a queued torrent has strictly higher priority (lower position) than the lowest-priority active torrent, swap them. One swap per category per tick to prevent cascade instability.

compute_seed_rank

Compute swarm demand rank for a seeding torrent.

evaluate

Evaluate the queue and decide which torrents to start/stop.

move_bottom

Move to last position (lowest priority). Returns changes.

move_down

Move one position down. Returns changes.

move_top

Move to position 0 (highest priority). Returns changes.

move_up

Move one position up (lower number = higher priority). Returns changes.

remove_position

Removes a position and shifts all positions above it down by 1. Returns the list of (info_hash, old_pos, new_pos) that changed.

set_position

Moves a torrent to a new absolute position. Shifts others to maintain density. Returns the list of (info_hash, old_pos, new_pos) for all changed entries.
