Struct RangeSetND 

pub struct RangeSetND {
    pub vecrangesets: Vec<Vec<RangeSet>>,
    /* private fields */
}

N-dimensional range set, used internally by NodeSet for multi-range patterns.

NOTE: unlike Python’s RangeSetND, no automatic n-dimensional folding (merging/sorting of overlapping vectors, i.e. precond_fold) is performed yet. Iteration and RangeSetND::index follow the stored vector order, so callers wanting Python-identical positions must store vectors already disjoint, merged, and ordered the way Python’s fold would leave them.

Fields

vecrangesets: Vec<Vec<RangeSet>>

Implementations

impl RangeSetND

pub fn new(autostep: Option<u32>) -> Self

pub fn from_rangesets( vecrangesets: Vec<Vec<RangeSet>>, autostep: Option<u32>, ) -> Self

Build from a vector of RangeSet vectors, mirroring Python’s RangeSetND([[rs1, rs2, ...], ...]).

pub fn len(&self) -> usize

Count elements as the sum of each vector’s Cartesian-product size.

Without nD folding this counts duplicate index vectors across overlapping stored vectors multiple times; Python’s __len__ folds first and counts unique vectors only.

pub fn is_empty(&self) -> bool

Whether the set contains no element.

pub fn iter(&self) -> impl Iterator<Item = Vec<String>> + '_

Iterate over all index vectors (as zero-padded strings) in iteration order: stored vectors in order, and within each vector the Cartesian product of its sorted RangeSets with the last dimension varying fastest (Python’s RangeSetND._iter()).

pub fn index<T: ToString>(&self, elem: &[T]) -> Option<usize>

Return the zero-based position of an index vector in iteration order, or None if absent (Python raises ValueError).

Ports Python’s RangeSetND.index() (ClusterShell commit 484d230), the reverse operation of RangeSetND.__getitem__. Elements may be strings (zero-padding is then significant) or integers; anything ToString covers mirrors Python’s "%s" % e conversion. Python’s TypeError for bare strings/scalars is a compile-time impossibility here since a slice of indexes is required.

pub fn index_within<T: ToString>( &self, elem: &[T], start: isize, stop: Option<isize>, ) -> Option<usize>

RangeSetND::index restricted to a search window, mirroring Python’s optional start/stop arguments (list.index() semantics; negative bounds count from the end).

Trait Implementations

impl Clone for RangeSetND

fn clone(&self) -> Self
