Struct Accessor

pub struct Accessor { /* private fields */ }

Rust wrapper around ABinderRpc_Accessor objects for RPC binder service management.

Dropping the Accessor will drop the underlying object and the binder it owns.

Implementations

impl Accessor

pub fn new<F>(instance: &str, callback: F) -> Accessor

where F: Fn(&str) -> Option<ConnectionInfo> + Send + Sync + 'static,

Create a new accessor that will call the given callback when its connection info is required. The callback object and all objects it captures are owned by the Accessor and will be deleted some time after the Accessor is Dropped. If the callback is being called when the Accessor is Dropped, the callback will not be deleted immediately.

pub fn from_binder(instance: &str, binder: SpIBinder) -> Option<Accessor>

Creates a new Accessor instance based on an existing Accessor’s binder. This is useful when the Accessor instance is hosted in another process that has the permissions to create the socket connection FD.

The instance argument must match the instance that the original Accessor is responsible for. instance must not contain null bytes and is used to create a CString to pass through FFI. The binder argument must be a valid binder from an Accessor

pub fn as_binder(&self) -> Option<SpIBinder>

Get the underlying binder for this Accessor for when it needs to be either registered with service manager or sent to another process.

Trait Implementations

impl Debug for Accessor

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

Formats the value using the given formatter.

impl Drop for Accessor

fn drop(&mut self)

Executes the destructor for this type.

impl Send for Accessor

Safety: A Accessor is a wrapper around ABinderRpc_Accessor which is Sync and Send. As ABinderRpc_Accessor is threadsafe, this structure is too. The Fn owned the Accessor has Sync and Send properties

impl Sync for Accessor

Safety: A Accessor is a wrapper around ABinderRpc_Accessor which is Sync and Send. As ABinderRpc_Accessor is threadsafe, this structure is too. The Fn owned the Accessor has Sync and Send properties
