Module exmex::prelude

To use the expression trait Express and its implementation FlatEx one can use exmex::prelude::*;.

Structs

FlatEx

This is the core data type representing a flattened expression and the result of parsing a string. We use flattened expressions to make efficient evaluation possible. Simplified, a flat expression consists of a SmallVec of nodes and a SmallVec of operators that are applied to the nodes in an order following operator priorities.

Traits

Express

Expressions implementing this trait can be evaluated for specific variable values, differentiated partially, and unparsed, i.e., transformed into a string representation.
