Struct SelectionPretty

pub struct SelectionPretty(/* private fields */);

A structured pretty-printer that renders Selection expressions in DSL constructor form.

This type implements SelectionSYM and emits expressions like all(range(0..4, true_())), which mirror the Rust-based DSL used to construct Selection values programmatically.

Internally used by [Selection::fmt] to support human-readable display of selection expressions in their canonical constructor form.

Use Selection::fold or the pretty helper to produce a SelectionPretty:

use ndslice::selection::dsl::*;
use ndslice::selection::pretty::pretty;
let expr = all(range(0..4, true_()));
println!("{}", pretty(&expr)); // prints: all(range(0..4, true_()))

Trait Implementations

impl Display for SelectionPretty

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl SelectionSYM for SelectionPretty

fn false_() -> SelectionPretty

The identity selection (matches no nodes).

fn true_() -> SelectionPretty

The universal selection (matches all nodes).

fn all(s: SelectionPretty) -> SelectionPretty

Selects all values along the current dimension, then applies the inner selection.

fn first(s: SelectionPretty) -> SelectionPretty

Selects the first index along the current dimension for which the inner selection is non-empty.

fn range<R>(range: R, s: SelectionPretty) -> SelectionPretty

where R: Into<Range>,

Selects values within the given range along the current dimension, then applies the inner selection.

fn label<L>(labels: Vec<L>, s: SelectionPretty) -> SelectionPretty

where L: Into<LabelKey>,

Selects values along the current dimension that match the given labels, then applies the inner selection.

fn any(s: SelectionPretty) -> SelectionPretty

Selects a random index along the current dimension, then applies the inner selection.

fn intersection(a: SelectionPretty, b: SelectionPretty) -> SelectionPretty

The intersection (logical AND) of two selection expressions.

fn union(a: SelectionPretty, b: SelectionPretty) -> SelectionPretty

The union (logical OR) of two selection expressions.
