pub struct LiteContinuousAggManager { /* private fields */ }Expand description
Lite continuous aggregate manager.
Processes (timestamp, value) flush buffers and maintains materialized
bucketed aggregates in memory.
Implementations§
Source§impl LiteContinuousAggManager
impl LiteContinuousAggManager
pub fn new() -> Self
Sourcepub fn register(&mut self, def: ContinuousAggDef)
pub fn register(&mut self, def: ContinuousAggDef)
Register a continuous aggregate definition.
Sourcepub fn unregister(&mut self, name: &str)
pub fn unregister(&mut self, name: &str)
Remove a continuous aggregate.
Sourcepub fn on_flush(
&mut self,
source_collection: &str,
timestamps: &[i64],
values: &[f64],
) -> Vec<String>
pub fn on_flush( &mut self, source_collection: &str, timestamps: &[i64], values: &[f64], ) -> Vec<String>
Process a flush event: compute bucketed aggregates from raw data.
Called after TimeseriesEngine::flush() with the flushed timestamps
and values. Incrementally updates materialized buckets.
Returns names of aggregates that were refreshed.
Sourcepub fn query(
&self,
agg_name: &str,
start_ms: i64,
end_ms: i64,
) -> Vec<&MaterializedBucket>
pub fn query( &self, agg_name: &str, start_ms: i64, end_ms: i64, ) -> Vec<&MaterializedBucket>
Query materialized buckets for an aggregate within a time range.
Sourcepub fn query_all(&self, agg_name: &str) -> Vec<&MaterializedBucket>
pub fn query_all(&self, agg_name: &str) -> Vec<&MaterializedBucket>
Get all materialized buckets for an aggregate, sorted by time.
Sourcepub fn apply_retention(&mut self, now_ms: i64) -> usize
pub fn apply_retention(&mut self, now_ms: i64) -> usize
Apply retention: remove buckets older than each aggregate’s retention period.

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().

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>
renamed to 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);
