Trait wasmi::FromRuntimeValue
source · [−]pub trait FromRuntimeValue where
Self: Sized, {
fn from_runtime_value(val: RuntimeValue) -> Option<Self>;
}
Expand description
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>
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.
Implementations on Foreign Types
sourceimpl FromRuntimeValue for bool
impl FromRuntimeValue for bool
This conversion assumes that boolean values are represented by
I32
type.
fn from_runtime_value(val: RuntimeValue) -> Option<Self>
sourceimpl FromRuntimeValue for i8
impl FromRuntimeValue for i8
This conversion assumes that i8
is represented as an I32
.
fn from_runtime_value(val: RuntimeValue) -> Option<Self>
sourceimpl FromRuntimeValue for i16
impl FromRuntimeValue for i16
This conversion assumes that i16
is represented as an I32
.
fn from_runtime_value(val: RuntimeValue) -> Option<Self>
sourceimpl FromRuntimeValue for u8
impl FromRuntimeValue for u8
This conversion assumes that u8
is represented as an I32
.
fn from_runtime_value(val: RuntimeValue) -> Option<Self>
sourceimpl FromRuntimeValue for u16
impl FromRuntimeValue for u16
This conversion assumes that u16
is represented as an I32
.
