Struct geo_aid::generator::expression::Expression

pub struct Expression<T> {
    pub weights: Weights,
    pub kind: T,
}

An expression is a base construct of Geo-AID. Contains a cache, saved weights and the expression kind itself.

Fields

weights: Weights

Saved weights

kind: T

Expression kind.

Implementations

impl<T: Evaluate + Kind> Expression<T>

where T::Output: From<Value> + Into<Value> + Clone,

pub fn new(expr: T, weight: FastFloat) -> Self

pub fn get_address(self: &Arc<Self>) -> usize

Gets the expressions address.

pub fn evaluate(self: &Arc<Self>, args: &EvaluationArgs<'_>) -> T::Output

Evaluates the expression.

Errors

Any errors related to failure when evaluating.

pub fn collect(self: &Arc<Self>, exprs: &mut Vec<usize>)

Collects expressions that should be cached.

pub fn is_trivial(&self) -> bool

Trivial expressions are ones that don’t require any calculations being made. Trivial expressions should not be cached, as it is much faster to evaluate them than to get their caches.

Trait Implementations

impl<T: Clone> Clone for Expression<T>

fn clone(&self) -> Expression<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Expression<T>

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

Formats the value using the given formatter.

impl<T> Serialize for Expression<T>

where T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
