Struct QftBuilder 

pub struct QftBuilder { /* private fields */ }

Builder for constructing QFT files with a fluent interface.

Example

use qft::QftBuilder;

let state = QftBuilder::new(4)
    .bond_dimension(128)
    .golay(true)
    .metadata("author", "Alice")
    .metadata("experiment", "VQE")
    .build()
    .unwrap();
