Expand description

This trait defines an abstract syntax without committing to a specific representation. It follow the tagless-final style where Selection is a default AST representation.

Required Methods§

Source

fn false_() -> Self

The identity selection (matches no nodes).

Source

fn true_() -> Self

The universal selection (matches all nodes).

Source

fn all(selection: Self) -> Self

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

Source

fn first(selection: Self) -> Self

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

Source

fn range<R: Into<Range>>(range: R, selection: Self) -> Self

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

Source

fn label<L: Into<LabelKey>>(labels: Vec<L>, selection: Self) -> Self

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

Source

fn any(selection: Self) -> Self

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

Source

fn intersection(lhs: Self, selection: Self) -> Self

The intersection (logical AND) of two selection expressions.

Source

fn union(lhs: Self, selection: Self) -> Self

The union (logical OR) of two selection expressions.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
