pub type Pointer<T> = Pointer<T>;

A raw pointer that can be used in a runtime interface function signature.

Aliased Type

pub struct Pointer<T> { /* private fields */ }

Trait Implementations

impl<'a, T: PointerType> FromFFIValue<'a> for Pointer<T>

Available on non-substrate_runtime only.

type Owned = Pointer<T>

The owned inner type.

fn from_ffi_value(_: &mut dyn FunctionContext, arg: u32) -> Result<Self>

Creates Self::Owned from the given arg received through the FFI boundary from the runtime.

fn take_from_owned(owned: &'a mut Self::Owned) -> Self::Inner

Creates Self::Inner from an owned value.

fn write_back_into_runtime( _value: Self::Owned, _context: &mut dyn FunctionContext, _arg: Self::FFIType, ) -> Result<()>

Write back a modified value back into the runtime’s memory.
