Macro json_forge 

json_forge!() { /* proc-macro */ }

Generate Rust data structures from a JSON file on disk.

Usage

json_forge! {
    path     = "relative/path/to/data.json",  // relative to CARGO_MANIFEST_DIR
    name     = "MyEntry",                      // name for the generated struct
    vis      = pub,                            // struct visibility (default: pub)
    data_vis = pub(crate),                     // data visibility  (default: same as vis)
    embedded = false,                          // override embedded mode
}

Visibility

Both vis and data_vis accept pub, pub(crate), pub(super), pub(self), or private (no visibility modifier). When data_vis is omitted it defaults to vis.

Embedded mode

Without the embedded feature (or embedded = false), this emits:

• A struct MyEntry { … } with owned field types (String, Vec<T>, etc.).
• A const MY_ENTRY_JSON: &str containing the raw JSON via include_str!.

With the embedded feature enabled (or embedded = true), this emits:

• A struct MyEntry { … } with &'static str / &'static [T] fields.
• A static MY_ENTRY: ::phf::Map<&'static str, MyEntry> (for top-level objects) or a fixed-length array static (for top-level arrays).

embedded = true requires the embedded Cargo feature; embedded = false forces runtime mode even when the feature is active.

Consumer note for embedded mode

The generated code references ::phf::Map. Add phf = "0.13" to the dependencies of the crate that invokes the macro.
