ResolvedLoadFactors

Struct ResolvedLoadFactors 

Source
pub struct ResolvedLoadFactors { /* private fields */ }
Expand description

Pre-resolved per-block load scaling factors.

Provides O(1) lookup of load block factors by (bus_index, stage_index, block_index). Returns 1.0 for absent entries (no scaling). Populated by cobre-io during the resolution step and stored in crate::System.

Uses dense 3D storage (n_buses * n_stages * max_blocks) initialized to 1.0. The total size is small (typically < 10K entries) and the lookup is on the LP-building hot path.

§Examples

use cobre_core::resolved::ResolvedLoadFactors;

let empty = ResolvedLoadFactors::empty();
assert!((empty.factor(0, 0, 0) - 1.0).abs() < f64::EPSILON);

Implementations§

Source§

impl ResolvedLoadFactors

Source

pub fn empty() -> Self

Create an empty load factors table. All lookups return 1.0.

Used as the default when no load_factors.json exists.

§Examples
use cobre_core::resolved::ResolvedLoadFactors;

let t = ResolvedLoadFactors::empty();
assert!((t.factor(5, 3, 2) - 1.0).abs() < f64::EPSILON);
Source

pub fn new(n_buses: usize, n_stages: usize, max_blocks: usize) -> Self

Create a new load factors table with the given dimensions.

All entries are initialized to 1.0 (no scaling). Use set to populate individual entries.

Source

pub fn set( &mut self, bus_idx: usize, stage_idx: usize, block_idx: usize, value: f64, )

Set the load factor for a specific (bus_idx, stage_idx, block_idx) triple.

§Panics

Panics if any index is out of bounds.

Source

pub fn factor(&self, bus_idx: usize, stage_idx: usize, block_idx: usize) -> f64

Look up the load factor for a (bus_idx, stage_idx, block_idx) triple.

Returns 1.0 when the index is out of bounds or the table is empty.
