Struct PackagedTraitObject

#[repr(C)]
pub struct PackagedTraitObject {
    pub trait_object: TraitObject,
    pub entry: unsafe extern "C" fn(flag: AbiProtocol),
}

A trait object together with its entry point

Fields

trait_object: TraitObject

Type erased trait object for an ABI-exported trait

entry: unsafe extern "C" fn(flag: AbiProtocol)

The low level entry point

Implementations

impl PackagedTraitObject

pub fn new<T: AbiExportable + ?Sized>(boxed: Box<T>) -> PackagedTraitObject

Create a PackagedTraitObject from a Box<T> . T must be a trait object. T must implement AbiExportable, which means it has an ::ABI_ENTRY associated type that gives the entry point.

pub fn new_from_ptr<T>(r: *const T) -> PackagedTraitObject

where T: AbiExportable + ?Sized,

Create a PackagedTraitObject from a &T. T must be a trait object. T must implement AbiExportable, which means it has an ::ABI_ENTRY associated type that gives the entry point. Note, we use *const T here even for mutable cases, but it doesn’t matter since it’s never used, it’s just cast to other stuff and then finally back to the right type.

pub fn serialize( self, serializer: &mut Serializer<'_, impl Write>, ) -> Result<(), SavefileError>

‘Serialize’ this object. I.e, write it to a binary buffer, so that we can send it to a foreign library.

pub unsafe fn deserialize( deserializer: &mut Deserializer<'_, impl Read>, ) -> Result<PackagedTraitObject, SavefileError>

‘Deserialize’ this object. I.e, read it from a binary buffer, so that we can receive it from a foreign library.

Safety

The data available to read from Deserializer must be correct, and contain a valid serialized PackagedTraitObject.
