Struct doors::server::Door

pub struct Door(_);

A Descriptor for the Door Server

When a door is created, the kernel hands us back a reference to it by giving us an index in our descriptor table. This is true even if the door hasn’t been attached to the filesystem yet, a la pipes or sockets.

Implementations

impl Door

pub fn create(sp: ServerProcedure) -> Result<Self, Error>

Create a new Door with the specified server procedure. This will not expose the door to the filesystem by default. It will assume that you are not using a door cookie, and that you do not need to set any DoorAttributes.

pub fn create_with_cookie( sp: ServerProcedure, cookie: u64 ) -> Result<Self, Error>

Create a new Door with a Cookie. This will not expose the door to the filesystem by default. It will use the door cookie that you provide, but will assume that you do not need to set any DoorAttributes.

pub fn create_with_attributes( sp: ServerProcedure, attrs: DoorAttributes ) -> Result<Self, Error>

Create a new Door with Attributes. This will not expose the door to the filesystem by default. It will use the DoorAttributes that you provide, but will assume that you are not using a door cookie.

pub fn create_with_cookie_and_attributes( sp: ServerProcedure, cookie: u64, attrs: DoorAttributes ) -> Result<Self, Error>

Create a new Door with Cookie and Attributes. This will not expose the door to the filesystem by default. It will use the DoorAttributes and cookie that you provide.

pub fn install<P: AsRef<Path>>(&self, path: P) -> Result<(), Error>

Make this door server available on the filesystem. This is necessary if we want other processes to be able to find and call this door server.

pub fn force_install<P: AsRef<Path>>(&self, path: P) -> Result<(), Error>

Make this door available on the filesystem even if there is already a file (possibly leftover from a previous door) as this path.
