Struct LodfColumnBuilder 

pub struct LodfColumnBuilder<'model, 'network> { /* private fields */ }

Lazily computes LODF columns from a prepared DC model.

This caches the solved reduced-bus basis columns needed to evaluate outage columns, so repeated compute_column() calls avoid recomputing the same endpoint solves. Use this for large-system workflows that need to process one outage column at a time without materializing a dense all-pairs matrix.

Implementations

impl<'model, 'network> LodfColumnBuilder<'model, 'network>

pub fn compute_column( &mut self, monitored_branch_indices: &[usize], outage_branch_idx: usize, ) -> Result<Vec<f64>, DcError>

Compute one LODF outage column for the requested monitored branch set.

The returned vector is ordered exactly like monitored_branch_indices. Entry i is LODF[monitored_branch_indices[i], outage_branch_idx].

pub fn stream_columns<F>( &mut self, monitored_branch_indices: &[usize], outage_branch_indices: &[usize], visit_column: F, ) -> Result<(), DcError>

where F: FnMut(usize, usize, &[f64]) -> Result<(), DcError>,

Visit a sequence of outage columns without materializing a matrix.
