Trait wasmi::FromRuntimeValue

pub trait FromRuntimeValue where
    Self: Sized, {
    fn from_runtime_value(val: RuntimeValue) -> Option<Self>;
}

Trait for creating value from a RuntimeValue.

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_runtime_value(val: RuntimeValue) -> Option<Self>

Create a value of type Self from a given RuntimeValue.

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