Struct FftPlanMany 

pub struct FftPlanMany {
    pub rank: u32,
    pub dims: [i32; 3],
    pub in_embed: Option<[i32; 3]>,
    pub in_stride: i32,
    pub in_dist: i32,
    pub out_embed: Option<[i32; 3]>,
    pub out_stride: i32,
    pub out_dist: i32,
    pub kind: FftKind,
    pub batch: i32,
}

Builder for advanced batched plans. Mirrors cufftPlanMany’s argument list: arbitrary rank (1, 2, or 3), per-dim sizes, optional in/out embed dims with strides and per-batch distances.

Use [FftPlanMany::build] (resolves through the LRU cache) or FftActor::ensure_plan to materialize an FftPlan.
