# SSVM wasi helper
## Usage
In the Cargo.toml
```toml
[dependencies]
ssvm-wasi-helper = "=0.1.3"
```
## To enable the wasi feature
In your wasi functions
```rs
use ssvm_wasi_helper::ssvm_wasi_helper::_initialize;
pub fn func1() {
_initialize();
// do something which is related to wasi environment variables, arguments, and preopens.
}
```
## To get string data from caller (with SSVM-go support)
```rs
use ssvm_wasi_helper::ssvm_wasi_helper::get_string_from_caller;
pub fn func1() {
let s = get_string_from_caller();
// do something with the string `s`
}
```
## To get byte array data from caller (with SSVM-go support)
```rs
use ssvm_wasi_helper::ssvm_wasi_helper::get_bytes_from_caller;
pub fn func1() {
let bs = get_bytes_from_caller();
// do something with the Vec<u8> `bs`
}
```
## To send string data to caller (with SSVM-go support)
```rs
use ssvm_wasi_helper::ssvm_wasi_helper::send_string_to_caller;
pub fn func1() {
let s = "hello";
send_string_to_caller(s);
}
```
## To get byte array data from caller (with SSVM-go support)
```rs
use ssvm_wasi_helper::ssvm_wasi_helper::send_bytes_to_caller;
pub fn func1() {
let bs = vec![0u8, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
send_bytes_to_caller(bs);
}
```
