Struct OftConfig 

pub struct OftConfig {
    pub r: usize,
    pub coft: bool,
    pub eps: f64,
    pub block_share: bool,
    pub target_modules: Vec<String>,
    pub use_exact_cayley: bool,
}

Configuration for OFT adapters.

Fields

r: usize

Number of OFT blocks (determines expressiveness vs efficiency).

coft: bool

Whether to use constrained OFT (COFT) which enforces strict orthogonality.

eps: f64

Small constant for numerical stability.

block_share: bool

Block sharing across layers.

target_modules: Vec<String>

Target modules to apply OFT to.

use_exact_cayley: bool

Whether to use exact Cayley transform computation.

When false (default), uses a Neumann series approximation (I + Q)^{-1} ≈ I - Q + Q^2 which is efficient but less accurate for larger Q values.

When true, computes the exact inverse using Newton-Schulz iteration, providing higher accuracy at the cost of additional computation.
