When attached to a function or a method, prevents wasm-bindgen from auto-generating JSDoc-style doc comments. By default, wasm-bindgen adds @param and @returns annotations to doc comments in the generated JS files. A skip_jsdoc annotation prevents this, allowing you to supply your own doc comments.

The following rust uses skip_jsdoc to omit one of the auto-generated doc comments.

# #![allow(unused_variables)]
#fn main() {
use wasm_bindgen::prelude::*;

/// Autogenerated docs.
#[wasm_bindgen]
pub fn foo(arg: u32) -> u32 { arg + 1 }

/// Manually written docs.
///
/// @param {number} arg - A descriptive description.
/// @returns {number} Something a bit bigger.
#[wasm_bindgen(skip_jsdoc)]
pub fn bar(arg: u32) -> u32 { arg + 2 }
#}

The wasm-bindgen-generated JS interface of the above code will look something like this:

/**
* Autogenerated docs.
*
* @param {number} arg
* @returns {number}
*/
export function foo(arg) { /* ... */ }

/**
* Manually written docs.
*
* @param {number} arg - A descriptive description.
* @returns {number} Something a bit bigger.
*/
export function bar(arg) { /* ... */ }
