The wrapper's formula manifest

A versioned record of what mixeff currently supports — formula syntax surface, schema versions per artifact type, and capability flags. The manifest is the wrapper's machine-readable answer to "what does this build know how to do?". Fitted objects do not carry the whole manifest: each one stamps the narrower fit$schema record (artifact schema name and version, crate version, package version), which the serialization and reporting paths read back. What lets audit() describe a fit after readRDS(), with no live Rust handle, is the durable compiled artifact stored beside it.

Usage

mm_formula_manifest()

Value

A named list with the following elements:

mixeff_rust_version

Version of the bundled extendr crate.

crate_version

Version of the bundled mixeff-rs upstream crate.

schema_versions

Named list, one entry per artifact schema the wrapper currently emits or consumes.

formula_features

Named list with operators, intercept_forms, random_term_forms, and transformations — the lme4-style syntax surface.

capabilities

Named list of logical flags (parse_formula, compile_model, audit_design, explain_model, random_options, compare_covariance, fit_lmm, fit_glmm, audit, changes, diagnostics, fit_status, parameterization, roles, as_json, simulate, inference, model_comparison_table, fit_summary_payload, marginal_quantity_table, marginal_quantities, verify_convergence). The marginal_quantity_table schema may be available before the corresponding marginal_quantities verbs are implemented.

Details

Capability flags evolve across releases; gate behavior on flags rather than on package version.

Examples

m <- mm_formula_manifest()
m$schema_versions$formula
#> [1] "v0"
m$capabilities$parse_formula
#> [1] TRUE
