Trait sp_runtime_interface::wasm::FromFFIValue [−][src]
pub trait FromFFIValue: Sized + RIType { fn from_ffi_value(arg: Self::FFIType) -> Self; }
Expand description
Something that can be created from a ffi value.
Safety
It is unsafe behavior to call Something::into_ffi_value().get()
and take this as input for
from_ffi_value
. Implementations are safe to assume that the arg
given to from_ffi_value
is only generated by the corresponding host::IntoFFIValue
implementation.
Required methods
fn from_ffi_value(arg: Self::FFIType) -> Self
fn from_ffi_value(arg: Self::FFIType) -> Self
Create Self
from the given ffi value.
