Struct RotationShape 

pub struct RotationShape {
    pub add_devices: Vec<CurveType>,
    pub remove_indices: Vec<u32>,
    pub new_kt: Option<Threshold>,
    pub new_nt: Option<Threshold>,
}

Shape of a rotation request: adds, removes, threshold changes.

A RotationShape::default() is a key-set-preserving rotation: same key count and thresholds, only the pre-committed next keys rotate in. Non-default variants drive multi-device topology changes (new device, removed device, threshold change).

Fields

add_devices: Vec<CurveType>

Curves for newly-added device slots. One fresh keypair is generated per entry and appended to the new k list.

remove_indices: Vec<u32>

Indices into the prior n commitment list to exclude from the new k list. Requires CESR indexed-signature support (tracked for a future pass); current validator rejects asymmetric rotations.

new_kt: Option<Threshold>

New signing threshold. None keeps the prior kt.

new_nt: Option<Threshold>

New next-rotation threshold. None keeps the prior nt.

Trait Implementations

impl Default for RotationShape

fn default() -> RotationShape

Returns the “default value” for a type.
