Struct wasmedge_sdk::Executor

pub struct Executor { /* private fields */ }

Defines an execution environment for both pure WASM and compiled WASM.

Implementations

impl Executor

pub fn new( config: Option<&Config>, stat: Option<&mut Statistics> ) -> WasmEdgeResult<Self>

Creates a new executor to be associated with the given config and statistics.

Arguments

• config specifies the configuration of the new executor.

• stat specifies the statistics needed by the new executor.

Error

If fail to create a executor, then an error is returned.

pub fn run_func( &self, func: &Func, params: impl IntoIterator<Item = WasmValue> ) -> WasmEdgeResult<Vec<WasmValue>>

Runs a host function instance and returns the results.

Arguments

• func - The function instance to run.

• params - The arguments to pass to the function.

Errors

If fail to run the host function, then an error is returned.

pub fn run_func_with_timeout( &self, func: &Func, params: impl IntoIterator<Item = WasmValue>, timeout: Duration ) -> WasmEdgeResult<Vec<WasmValue>>

Available on Linux and non-musl only.

Runs a host function instance with a timeout setting.

Arguments

• func - The function instance to run.

• params - The arguments to pass to the function.

• timeout - The maximum execution time of the function to be run.

Errors

If fail to run the host function, then an error is returned.

pub async fn run_func_async( &self, async_state: &AsyncState, func: &Func, params: impl IntoIterator<Item = WasmValue> + Send ) -> WasmEdgeResult<Vec<WasmValue>>

Available on crate feature async and Linux only.

Asynchronously runs a host function instance and returns the results.

Arguments

• func - The function instance to run.

• params - The arguments to pass to the function.

Errors

If fail to run the host function, then an error is returned.

pub async fn run_func_async_with_timeout( &self, async_state: &AsyncState, func: &Func, params: impl IntoIterator<Item = WasmValue> + Send, timeout: Duration ) -> WasmEdgeResult<Vec<WasmValue>>

Available on crate feature async and Linux and non-musl only.

Asynchronously runs a host function instance with a timeout setting.

Arguments

• async_state - Used to store asynchronous state at run time.

• func - The function instance to run.

• params - The arguments to pass to the function.

• timeout - The maximum execution time of the function to be run.

Errors

If fail to run the host function, then an error is returned.

pub fn run_func_ref( &self, func_ref: &FuncRef, params: impl IntoIterator<Item = WasmValue> ) -> WasmEdgeResult<Vec<WasmValue>>

Runs a host function reference instance and returns the results.

Arguments

• func_ref - The function reference instance to run.

• params - The arguments to pass to the function.

Errors

If fail to run the host function reference instance, then an error is returned.

pub async fn run_func_ref_async( &self, async_state: &AsyncState, func_ref: &FuncRef, params: impl IntoIterator<Item = WasmValue> + Send ) -> WasmEdgeResult<Vec<WasmValue>>

Available on crate feature async and Linux only.

Asynchronously runs a host function reference instance and returns the results.

Arguments

• func_ref - The function reference instance to run.

• params - The arguments to pass to the function.

Errors

If fail to run the host function reference instance, then an error is returned.
