Trait wasmi_core::FromValue

pub trait FromValuewhere
    Self: Sized,{
    // Required method
    fn from_value(val: Value) -> Option<Self>;
}

Trait for creating value from a Value.

Typically each implementation can create a value from the specific type. For example, values of type bool or u32 are both represented by I32 and f64 values are represented by F64.

Required Methods

fn from_value(val: Value) -> Option<Self>

Create a value of type Self from a given Value.

Returns None if the Value is of type different than expected by the conversion in question.

Implementations on Foreign Types

impl FromValue for i64

fn from_value(val: Value) -> Option<Self>

impl FromValue for i16

This conversion assumes that i16 is represented as an I32.

impl FromValue for i8

This conversion assumes that i8 is represented as an I32.

fn from_value(val: Value) -> Option<Self>

impl FromValue for u32

fn from_value(val: Value) -> Option<Self>

impl FromValue for bool

This conversion assumes that boolean values are represented by I32 type.

fn from_value(val: Value) -> Option<Self>

impl FromValue for u8

This conversion assumes that u8 is represented as an I32.
