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:
- Ignite
- Liftoff
- Request
- Response
- Shutdown
Two Kind structures can be ord together to represent a combination. For
instance, to represent a fairing that is both an ignite and request fairing,
use Kind::Ignite | Kind::Request. Similarly, to represent a fairing that
is only an ignite fairing, use Kind::Ignite.
Additionally, a fairing can request to be treated as a
singleton by specifying the
Singleton kind.
Implementations§
Source§impl Kind
impl Kind
Sourcepub fn is(self, other: Kind) -> bool
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 ignite_and_req = Kind::Ignite | Kind::Request;
assert!(ignite_and_req.is(Kind::Ignite | Kind::Request));
assert!(ignite_and_req.is(Kind::Ignite));
assert!(ignite_and_req.is(Kind::Request));
assert!(!ignite_and_req.is(Kind::Liftoff));
assert!(!ignite_and_req.is(Kind::Response));
assert!(!ignite_and_req.is(Kind::Ignite | Kind::Response));
assert!(!ignite_and_req.is(Kind::Ignite | Kind::Request | Kind::Response));Sourcepub fn is_exactly(self, other: Kind) -> bool
pub fn is_exactly(self, other: Kind) -> bool
Returns true if self is exactly other.
§Example
use rocket::fairing::Kind;
let ignite_and_req = Kind::Ignite | Kind::Request;
assert!(ignite_and_req.is_exactly(Kind::Ignite | Kind::Request));
assert!(!ignite_and_req.is_exactly(Kind::Ignite));
assert!(!ignite_and_req.is_exactly(Kind::Request));
assert!(!ignite_and_req.is_exactly(Kind::Response));

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Returns a styled value derived from self with the background set to
value.

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
