oximo-macros

Internal procedural macros backing oximo's modeling surface: variable!, constraint!, soc_constraint!, objective!, sum!, set!, and param!.

This crate is an implementation detail, do not depend on it directly. The macros are re-exported through oximo-core and oximo::prelude, which is the supported entry point:

use oximo::prelude::*;

The macros expand to the typed builder API in oximo-core (Model, Set, Expr, sum_over, ...). See the oximo crate docs for the macro grammar and examples.

Sums inside constraint!, soc_constraint!, and objective! inherit the model's expression context and return 0 for empty domains or filters. For standalone sums, use sum!(model, body for i in domain) to supply that context explicitly. Nested sums inherit it, and selected terms are checked for model ownership. Standalone unanchored sums still require at least one term.
