}

An opened connection to a binder driver.

Variants

SetVmo

Set the VMO to used as a share resource between the driver and the client. mapped_address is the address where the vmo is mapped in the client address space.

The driver handles the other requests of the client concurrently, so it can handle an ioctl before the VMO is mapped. Clients should use MapVmo instead.

Fields

vmo: Vmo

mapped_address: u64

control_handle: BinderControlHandle

MapVmo

Maps the VMO used as a shared resource between the driver and the client. mapped_address is the address where the VMO is mapped in the client address space.

Responds once the VMO is mapped. The driver handles the other requests of the client concurrently, so the client must wait for the response before sending any ioctl that needs the VMO.

Fields

vmo: Vmo

mapped_address: u64

responder: BinderMapVmoResponder

Ioctl

Processes a Binder ioctl. This message returns writes for the calling thread that must be processed to correctly handle the ioctl.

Fields

tid: u64

request: u32

arg: u64

vmo: Vmo

ioctl_reads: Vec<IoctlReadWrite>

files: Vec<FileHandle>

responder: BinderIoctlResponder

RegisterThreadChannel

Registers a dedicated 1:1 channel for synchronous Binder transactions.

Fields

server_end: ServerEnd<BinderThreadMarker>

responder: BinderRegisterThreadChannelResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: BinderControlHandle

method_type: MethodType
