pub struct DeploymentStateHandle {
inner: Arc<Mutex<DeploymentStateInner>>,
}Expand description
A cloneable handle to a DeploymentState.
This should be held by modules providing external interfaces to
environmentd (e.g., the HTTP server). It provides methods to inspect the
current leadership state, and to promote the deployment to the leader if it
is ready to do so.
Fields§
§inner: Arc<Mutex<DeploymentStateInner>>Implementations§
Source§impl DeploymentStateHandle
impl DeploymentStateHandle
Sourcepub fn status(&self) -> DeploymentStatus
pub fn status(&self) -> DeploymentStatus
Returns the current deployment status.
Sourcepub fn try_skip_catchup(&self) -> Result<(), ()>
pub fn try_skip_catchup(&self) -> Result<(), ()>
Attempts to skip the catchup phase for the deployment.
Deployments in the Initializing phase cannot have their catchup phase
skipped. Deployments in the ReadyToPromote, Promoting, and
IsLeader states can be promoted (with the latter two cases being
no-ops).
If skipping the catchup was successful, returns Ok. Otherwise, returns
Err.
Sourcepub fn try_promote(&self) -> Result<(), ()>
pub fn try_promote(&self) -> Result<(), ()>
Attempts to promote this deployment to the leader.
Deployments in the Initializing or CatchingUp state cannot be
promoted. Deployments in the ReadyToPromote, Promoting, and
IsLeader states can be promoted (with the latter two cases being
no-ops).
If the leader was successfully promoted, returns Ok. Otherwise,
returns Err.

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().

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

Source§fn attr(&self, value: Attribute) -> Painted<&T>
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().

painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

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().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎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);Source§impl<T> Pipe for Twhere
