pub struct ConfigurationSystem { /* private fields */ }Expand description
The runtime configuration, translated from the raw sources and kept current.
The configuration system is the single owner of the Datadog Agent’s ConfigUpdate stream. It
folds each update onto the local source base to build the typed [SalukiConfiguration] directly,
and forwards the same update to a legacy [GenericConfiguration] compatibility map so
un-migrated components can still read by key. The current configuration lives in an ArcSwap
cell so readers load a whole, self-consistent version with no lock, while the update task
replaces it in one atomic store.
Implementations§
Source§impl ConfigurationSystem
impl ConfigurationSystem
Sourcepub fn live<T>(
&self,
project: impl for<'a> Fn(&'a SalukiConfiguration) -> &'a T + Send + Sync + 'static,
) -> Live<T>
pub fn live<T>( &self, project: impl for<'a> Fn(&'a SalukiConfiguration) -> &'a T + Send + Sync + 'static, ) -> Live<T>
Returns a live view of the given projection of the current configuration. Narrow further with
[Live::project]. This is the only way a consumer subscribes to runtime updates.
Sourcepub fn config(&self) -> Guard<Arc<SalukiConfiguration>>
pub fn config(&self) -> Guard<Arc<SalukiConfiguration>>
Loads the current translated configuration.
The returned guard pins one whole version; a concurrent refresh never tears the read.
Sourcepub fn current_handle(&self) -> Arc<ArcSwap<SalukiConfiguration>>
pub fn current_handle(&self) -> Arc<ArcSwap<SalukiConfiguration>>
Returns a shared handle to the current-configuration cell for readers that load it independently.

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>

Source§fn bg(&self, value: Color) -> Painted<&T>
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().
use yansi::Paint;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

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

Source§fn quirk(&self, value: Quirk) -> 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);
