# wasm-bindgen-utils
Provides utilities, helpers and macros to easily build and customize `wasm_bindgen` bindings. For more details please read the doumentation of the items of this lib.
Example:
```rust
use wasm_bindgen_utils::{prelude::*, impl_wasm_traits, impl_custom_tsify, add_ts_content};
#[derive(Serialize, Deserialize)]
#[serde(rename_all = "camelCase")]
pub struct SomeType {
#[cfg_attr(target_family = "wasm", serde(serialize_with = "serialize_as_bytes"))]
pub field: Vec,
#[cfg_attr(target_family = "wasm", serde(serialize_with = "serialize_hashmap_as_object"))]
pub other_field: HashMap,
}
// impl wasm traits for SomeType
impl_wasm_traits!(SomeType);
// impl tsify manually for SomeType (as an alternative to Tsify derive macro)
// the given string literal will become the typescript interface bindings for SomeType
impl_custom_tsify!(
SomeType,
"export interface SomeType {
field: Uint8Array;
otherField: Record;
}"
);
// appends a custom section to the .d.ts generated bindings
add_ts_content!("import { Something } from 'some-js-lib'")
// now someType can be used on functions and methods natively
#[wasm_bindgen]
pub fn some_fn(arg: SomeType) -> String {
// body
}
#[wasm_bindgen]
pub async fn some_other_fn(arg1: Vec, arg2: HashMap) -> Result {
// body
Ok(SomeType {
field: arg1,
other_field: arg2
})
}
```
