Struct ArrowTrustRegionOptions 

Source 
pub struct ArrowTrustRegionOptions {
    pub radius: f64,
    pub steihaug_relative_tolerance: f64,
    pub max_iterations: usize,
}
Expand description

Trust-region controls for Steihaug-CG on the reduced BA system.

This is the Ceres-style guard around LM: ridge_t/ridge_beta provide Levenberg damping, while the trust radius bounds the reduced shared step in Euclidean β coordinates using Steihaug’s truncated-CG stopping rules for boundary hits and negative curvature.
