Modules

bytecode

Stack-machine bytecode for MD2 per-point / per-pixel hot loops.

carry

Carry-dependency analysis for per-point equation blocks.

compiled_block

Compiled block: bundles a Vec<Node> (evalexpr fallback) with an optional CompiledBytecode lowering.

context

Execution context for Milkdrop expressions.

error

Error types for the onedrop-eval crate.

evaluator

Evaluator for Milkdrop expressions.

math_functions

Mathematical functions for MilkDrop expressions.

Structs

Node

A node in the operator tree. The operator tree is created by the crate-level build_operator_tree method. It can be evaluated for a given context with the Node::eval method.

Functions

eval_simple

Evaluate a simple expression with default context.
