Module binder_impl

Advanced Binder APIs needed internally by AIDL or when manually using Binder without AIDL.

Structs

Binder

Rust wrapper around Binder remotable objects.

BorrowedParcel

Container for a message (data and object references) that can be sent through Binder.

InterfaceClass

Opaque reference to the type of a Binder interface.

Parcel

Container for a message (data and object references) that can be sent through Binder.

Enums

LocalStabilityType

Stability::Local.

Stability

Interface stability promise

VintfStabilityType

Stability::Vintf.

Constants

FIRST_CALL_TRANSACTION

First transaction code available for user commands (inclusive)

FLAG_CLEAR_BUF

Corresponds to TF_CLEAR_BUF – clear transaction buffers after call is made.

FLAG_ONEWAY

Corresponds to TF_ONE_WAY – an asynchronous call.

FLAG_PRIVATE_LOCAL

Set to the vendor flag if we are building for the VNDK, 0 otherwise

LAST_CALL_TRANSACTION

Last transaction code available for user commands (inclusive)

NON_NULL_PARCELABLE_FLAG

Flag that specifies that the following parcelable is present.

NULL_PARCELABLE_FLAG

Flag that specifies that the following parcelable is absent.

Traits

AssociateClass

An object that can be associate with an InterfaceClass.

BinderAsyncRuntime

A runtime for executing an async binder server.

Deserialize

A struct whose instances can be restored from a crate::parcel::Parcel.

DeserializeArray

Helper trait for types that can be deserialized as arrays. Defaults to calling Deserialize::deserialize() manually for every element, but can be overridden for custom implementations like readByteArray.

DeserializeOption

Helper trait for types that can be nullable when deserialized.

IBinderInternal

Internal interface of binder local or remote objects for making transactions.

ParcelableMetadata

Metadata that ParcelableHolder needs for all parcelables.

Proxy

Generic interface to remote binder objects.

Remotable

A local service that can be remotable via Binder.

Serialize

A struct whose instances can be written to a crate::parcel::Parcel.

SerializeArray

Helper trait for types that can be serialized as arrays. Defaults to calling Serialize::serialize() manually for every element, but can be overridden for custom implementations like writeByteArray.

SerializeOption

Helper trait for types that can be nullable when serialized.

StabilityType

Same as Stability, but in the form of a trait. Used when the stability should be encoded in the type.

ToAsyncInterface

Implemented by sync interfaces to specify what the associated async interface is. Generic to handle the fact that async interfaces are generic over a thread pool.

ToSyncInterface

Implemented by async interfaces to specify what the associated sync interface is.

UnstructuredParcelable

Super-trait for unstructured Binder parcelables, i.e. those implemented manually.

Type Aliases

TransactionCode

Binder action to perform.

TransactionFlags

Additional operation flags.

status_t

One of the STATUS_* values.
