Trait Implementations

impl Clone for StorageChanges

fn clone(&self) -> StorageChanges

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<UT> ConvertError<UT> for StorageChanges

impl Default for StorageChanges

fn default() -> StorageChanges

Returns the “default value” for a type.

impl<UT> FfiConverter<UT> for StorageChanges

const TYPE_ID_META: MetadataBuffer = _

Type ID metadata, serialized into a [MetadataBuffer].

type FfiType = RustBuffer

The low-level type used for passing values of this type over the FFI.

fn lower(v: Self) -> RustBuffer

Lower a rust value of the target type, into an FFI value of type Self::FfiType.

fn try_lift(buf: RustBuffer) -> Result<Self>

Lift a rust value of the target type, from an FFI value of type Self::FfiType.

fn write(obj: Self, buf: &mut Vec<u8>)

Write a rust value into a buffer, to send over the FFI in serialized form.

fn try_read(buf: &mut &[u8]) -> Result<Self>

Read a rust value from a buffer, received over the FFI in serialized form.

impl<UT> Lift<UT> for StorageChanges

type FfiType = <StorageChanges as FfiConverter<UT>>::FfiType

fn try_lift(v: Self::FfiType) -> Result<Self>

fn try_read(buf: &mut &[u8]) -> Result<Self>

fn try_lift_from_rust_buffer(v: RustBuffer) -> Result<Self, Error>

Convenience method

impl<UT> LiftRef<UT> for StorageChanges

type LiftType = StorageChanges

impl<UT> LiftReturn<UT> for StorageChanges

type ReturnType = <StorageChanges as Lift<UT>>::FfiType

FFI return type for trait interfaces

fn try_lift_successful_return(v: Self::ReturnType) -> Result<Self>

Lift a successfully returned value from a trait interface

fn lift_foreign_return( ffi_return: Self::ReturnType, call_status: RustCallStatus, ) -> Self

Lift a foreign returned value from a trait interface

fn lift_error(_buf: RustBuffer) -> Self

Lift a Rust value for a callback interface method error result

fn handle_callback_unexpected_error(e: UnexpectedUniFFICallbackError) -> Self

Lift a Rust value for an unexpected callback interface error

impl<UT> Lower<UT> for StorageChanges

type FfiType = <StorageChanges as FfiConverter<UT>>::FfiType

fn lower(obj: Self) -> Self::FfiType

fn write(obj: Self, buf: &mut Vec<u8>)

fn lower_into_rust_buffer(obj: Self) -> RustBuffer

Convenience method

impl<UT> LowerError<UT> for StorageChanges

fn lower_error(obj: Self) -> RustBuffer

Lower this value for scaffolding function return

impl<UT> LowerReturn<UT> for StorageChanges

type ReturnType = <StorageChanges as Lower<UT>>::FfiType

The type that should be returned by scaffolding functions for this type.

fn lower_return(v: Self) -> Result<Self::ReturnType, RustCallError>

Lower the return value from an scaffolding call

fn handle_failed_lift( error: LiftArgsError, ) -> Result<Self::ReturnType, RustCallError>

Lower the return value for failed argument lifts

impl PartialEq for StorageChanges

fn eq(&self, other: &StorageChanges) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StorageChanges

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
