Struct TruncationOptions 

pub struct TruncationOptions { /* private fields */ }

Options for truncation operations.

Builder Pattern

use tensor4all_core::SvdTruncationPolicy;
use tensor4all_treetn::TruncationOptions;

let options = TruncationOptions::default()
    .with_max_rank(50)
    .with_svd_policy(SvdTruncationPolicy::new(1e-10));

assert_eq!(options.max_rank(), Some(50));
assert_eq!(options.svd_policy(), Some(SvdTruncationPolicy::new(1e-10)));

Implementations

impl TruncationOptions

pub fn new() -> Self

Create options with default settings (no truncation limits).

pub fn with_max_rank(self, rank: usize) -> Self

Create options with a maximum rank.

pub fn with_svd_policy(self, policy: SvdTruncationPolicy) -> Self

Set the SVD truncation policy used during the truncation sweep.

pub fn svd_policy(&self) -> Option<SvdTruncationPolicy>

Get the SVD truncation policy.

pub fn max_rank(&self) -> Option<usize>

Get max_rank.
