Struct ProbeView

    pub n_vars: usize,
    pub m_rows: usize,
    pub jac_irow: &'a [Index],

}

View into the data we need to build an EqualityIncidence. Decoupled from TNLP itself so this module stays unit-testable without spinning up a full inner problem.

Fields

n_vars: usize

Number of variables.

m_rows: usize

Number of inner constraint rows.

jac_irow: &'a [Index]

Inner Jacobian sparsity (one entry per structural nonzero).

jac_jcol: &'a [Index]

jac_values: Option<&'a [Number]>

Optional Jacobian values at a probe point. When provided, entries that evaluate to exactly 0.0 are dropped — this removes structural zeros that linearity hasn’t already excluded.

g_l: &'a [Number]

g_u: &'a [Number]

linearity: Option<&'a [Linearity]>

Optional per-row linearity tags; unused by PR 2 but plumbed for PR 5’s coupling classifier.

one_based: bool

true when the inner TNLP uses Fortran (1-based) indexing.

eq_tol: Number

Tolerance for g_l[i] == g_u[i]. Rows tighter than this are treated as equalities.

excluded_vars: Option<&'a [bool]>

PR 13: per-variable mask. true entries are excluded from the incidence graph. Used to drop trivially-fixed variables (x_l[i] == x_u[i]) before matching.

excluded_rows: Option<&'a [bool]>

PR 13: per-row mask. true entries are excluded from the incidence graph. Used to drop free rows and trivially-slack inequalities before matching.
