Struct WasmValue

pub struct WasmValue { /* private fields */ }

Defines a WebAssembly value.

Implementations

impl WasmValue

pub fn as_raw(&self) -> WasmEdge_Value

Returns the raw WasmEdge_Value.

pub fn ty(&self) -> ValType

Returns the type of a WasmValue.

pub fn from_i32(val: i32) -> Self

Creates a WasmValue from a i32 value.

Argument

• val - The source i32 value.

pub fn to_i32(&self) -> i32

Generates a i32 value from a WasmValue.

pub fn from_i64(val: i64) -> Self

Creates a WasmValue from a i64 value.

Argument

• val - The source i64 value.

pub fn to_i64(&self) -> i64

Generates a i64 value from a WasmValue.

pub fn from_f32(val: f32) -> Self

Creates a WasmValue from a f32 value.

Argument

• val - The source f32 value.

pub fn to_f32(&self) -> f32

Generates a f32 value from a WasmValue.

pub fn from_f64(val: f64) -> Self

Creates a WasmValue from a f64 value.

Argument

• val - The source f64 value.

pub fn to_f64(&self) -> f64

Generates a f64 value from a WasmValue.

pub fn from_v128(val: i128) -> Self

Creates a WasmValue from a i128 value.

Argument

• val - The source i128 value.

pub fn to_v128(&self) -> i128

Generates a v128 value from a WasmValue.

pub fn is_null_ref(&self) -> bool

Checks if a WasmValue is NullRef or not.

pub fn from_func_ref<Func: AsFunc>(func_ref: &Func) -> Self

Creates a WasmValue from a FuncRef.

Notice that the WasmValues generated from FuncRefs are only meaningful when the bulk_memory_operations or reference_types option is enabled in the Config.

Argument

• func_ref - A FuncRef instance.

pub fn func_ref(&self) -> Option<FuncRef<&Self>>

Returns the FuncRef(crate::FuncRef).

If the WasmValue is a NullRef, then None is returned.

pub fn from_extern_ref<T>(extern_obj: &mut T) -> Self

Creates a WasmValue from a reference to an external object.

The WasmValues generated by this function are only meaningful when the reference_types option is enabled in the Config.

Argument

• extern_obj - The reference to an external object.

pub fn null_extern_ref() -> Self

Creates a null WasmValue with a ExternRef.

Argument

• val - The [RefType`] value.

pub fn extern_ref<T>(&self) -> Option<&T>

Returns the reference to an external object.

If the WasmValue is a NullRef, then None is returned.
