Struct WasiClocks 

pub struct WasiClocks;

A helper struct which implements HasData for the wasi:clocks APIs.

This can be useful when directly calling add_to_linker functions directly, such as [wasmtime_wasi::p2::bindings::clocks::monotonic_clock::add_to_linker] as the D type parameter. See HasData for more information about the type parameter’s purpose.

When using this type you can skip the WasiClocksView trait, for example.

Examples

use wasmtime::component::{Linker, ResourceTable};
use wasmtime::{Engine, Result, Config};
use wasmtime_wasi::clocks::*;

struct MyStoreState {
    table: ResourceTable,
    clocks: WasiClocksCtx,
}

fn main() -> Result<()> {
    let mut config = Config::new();
    config.async_support(true);
    let engine = Engine::new(&config)?;
    let mut linker = Linker::new(&engine);

    wasmtime_wasi::p2::bindings::clocks::monotonic_clock::add_to_linker::<MyStoreState, WasiClocks>(
        &mut linker,
        |state| WasiClocksCtxView {
            table: &mut state.table,
            ctx: &mut state.clocks,
        },
    )?;
    Ok(())
}
