storelib_rs 0.1.5

//! JS bindings produced by `wasm-bindgen`.
//!
//! Exposes the full library surface — handlers, helpers, and value types — to
//! JavaScript consumers. Enum-typed parameters are accepted as camelCase
//! strings, Market/Lang as their canonical wire form (e.g. `"US"`, `"en-US"`),
//! and complex values cross the FFI boundary as plain JS objects via
//! `serde-wasm-bindgen`.
