Struct PlanCombinator 

pub struct PlanCombinator {
    pub name: &'static str,
    pub min_children: usize,
    pub max_children: usize,
    pub keywords: &'static [&'static str],
    pub executable_now: bool,
}

Static description of a plan combinator: its name and structural constraints.

Fields

name: &'static str

Combinator name without the plan/ prefix (for example race).

min_children: usize

Minimum number of child plans the combinator accepts.

max_children: usize

Maximum number of child plans the combinator accepts.

keywords: &'static [&'static str]

Keyword argument names the combinator recognizes.

executable_now: bool

Whether the combinator can be executed by the current evaluator.

Trait Implementations

impl Clone for PlanCombinator

fn clone(&self) -> PlanCombinator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlanCombinator

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

Formats the value using the given formatter.

impl Eq for PlanCombinator

impl PartialEq for PlanCombinator

fn eq(&self, other: &PlanCombinator) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
