Trait Implementations

impl Clone for PersistableBundle

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PersistableBundle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PersistableBundle

fn default() -> Self

Returns the “default value” for a type.

impl Deserialize for PersistableBundle

type UninitType = Option<PersistableBundle>

Type for the uninitialized value of this type. Will be either Self if the type implements Default, Option<Self> otherwise.

fn uninit() -> Self::UninitType

Return an uninitialized or default-initialized value for this type.

fn from_init(value: Self) -> Self::UninitType

Convert an initialized value of type Self into Self::UninitType.

fn deserialize(parcel: &BorrowedParcel<'_>) -> Result<Self, StatusCode>

Deserialize an instance from the given crate::parcel::Parcel.

fn deserialize_from( &mut self, parcel: &BorrowedParcel<'_>, ) -> Result<(), StatusCode>

Deserialize an instance from the given crate::parcel::Parcel onto the current object. This operation will overwrite the old value partially or completely, depending on how much data is available.

const ASSERT_UNINIT_SIZE_AND_ALIGNMENT: bool = _

Assert at compile-time that Self and Self::UninitType have the same size and alignment. This will either fail to compile or evaluate to true. The only two macros that work here are panic! and assert!, so we cannot use assert_eq!.

impl DeserializeArray for PersistableBundle

fn deserialize_array( parcel: &BorrowedParcel<'_>, ) -> Result<Option<Vec<Self>>, StatusCode>

Deserialize an array of type from the given parcel.

impl DeserializeOption for PersistableBundle

fn deserialize_option( parcel: &BorrowedParcel<'_>, ) -> Result<Option<Self>, StatusCode>

Deserialize an Option of this type from the given parcel.

fn deserialize_option_from( this: &mut Option<Self>, parcel: &BorrowedParcel<'_>, ) -> Result<(), StatusCode>

Deserialize an Option of this type from the given parcel onto the current object. This operation will overwrite the current value partially or completely, depending on how much data is available.

impl Drop for PersistableBundle

fn drop(&mut self)
