Struct rocket::fairing::Kind

source ·
pub struct Kind(/* private fields */);
Expand description

A bitset representing the kinds of callbacks a Fairing wishes to receive.

A fairing can request any combination of any of the following kinds of callbacks:

  • Attach
  • Launch
  • Request
  • Response

Two Kind structures can be ord together to represent a combination. For instance, to represent a fairing that is both a launch and request fairing, use Kind::Launch | Kind::Request. Similarly, to represent a fairing that is only an attach fairing, use Kind::Attach.

Implementations§

source§

impl Kind

source

pub const Attach: Kind = _

Kind flag representing a request for an ‘attach’ callback.

source

pub const Launch: Kind = _

Kind flag representing a request for a ‘launch’ callback.

source

pub const Request: Kind = _

Kind flag representing a request for a ‘request’ callback.

source

pub const Response: Kind = _

Kind flag representing a request for a ‘response’ callback.

source

pub fn is(self, other: Kind) -> bool

Returns true if self is a superset of other. In other words, returns true if all of the kinds in other are also in self.

§Example
use rocket::fairing::Kind;

let launch_and_req = Kind::Launch | Kind::Request;
assert!(launch_and_req.is(Kind::Launch | Kind::Request));

assert!(launch_and_req.is(Kind::Launch));
assert!(launch_and_req.is(Kind::Request));

assert!(!launch_and_req.is(Kind::Response));
assert!(!launch_and_req.is(Kind::Launch | Kind::Response));
assert!(!launch_and_req.is(Kind::Launch | Kind::Request | Kind::Response));
source

pub fn is_exactly(self, other: Kind) -> bool

Returns true if self is exactly other.

§Example
use rocket::fairing::Kind;

let launch_and_req = Kind::Launch | Kind::Request;
assert!(launch_and_req.is_exactly(Kind::Launch | Kind::Request));

assert!(!launch_and_req.is_exactly(Kind::Launch));
assert!(!launch_and_req.is_exactly(Kind::Request));
assert!(!launch_and_req.is_exactly(Kind::Response));
assert!(!launch_and_req.is_exactly(Kind::Launch | Kind::Response));
