About
This crate only export a macro named #[wasmedge_bindgen] that used for retouching exporting functions to make it support more data types.
Data Types
Parameters
You can set the parameters to any one of the following types:
- Scalar Types: i8, u8, i16, u16, i32, u32, i64, u64, f32, f64, bool, char
- String
- Vec: Vec<i8>, Vec<u8>, Vec<i16>, Vec<u16>, Vec<i32>, Vec<u32>, Vec<i64>, Vec<u64>
Return Values
You can set the return values to any one of the following types:
- Scalar Types: i8, u8, i16, u16, i32, u32, i64, u64, f32, f64, bool, char
- String
- Vec: Vec<i8>, Vec<u8>, Vec<i16>, Vec<u16>, Vec<i32>, Vec<u32>, Vec<i64>, Vec<u64>
- Tuple Type: compounded by any number of the above three types
- Result: Ok<any one of the above four types>, Err<String>
The only way to tell the host that the error has occurred is to return Err<String> of Result.
Examples
#[wasmedge_bindgen]
pub fn create_line(p1: String, p2: String, desc: String) -> String
#[wasmedge_bindgen]
pub fn lowest_common_multiple(a: i32, b: i32) -> i32
#[wasmedge_bindgen]
pub fn sha3_digest(v: Vec<u8>) -> Vec<u8>
#[wasmedge_bindgen]
pub fn info(v: Vec<u8>) -> Result<(u8, String), String>
