Implementations§
Source§impl QueryStats
impl QueryStats
Sourcepub fn update_graph_selectivity(&self, matched: u64, total: u64)
pub fn update_graph_selectivity(&self, matched: u64, total: u64)
Updates graph selectivity estimate.
Sourcepub fn graph_selectivity(&self) -> f64
pub fn graph_selectivity(&self) -> f64
Gets the current graph selectivity estimate (0.0-1.0).
Sourcepub fn update_vector_latency(&self, latency_us: u64)
pub fn update_vector_latency(&self, latency_us: u64)
Updates average vector search latency using exponential moving average.
Uses EMA with α=0.1 for thread-safe updates without race conditions. EMA formula: new_avg = α * latency + (1-α) * old_avg This avoids the race condition in running average calculations.
Sourcepub fn update_graph_latency(&self, latency_us: u64)
pub fn update_graph_latency(&self, latency_us: u64)
Updates average graph traversal latency using exponential moving average.
Uses EMA with α=0.1 for thread-safe updates without race conditions. This ensures accurate statistics for query planning decisions.
Sourcepub fn avg_vector_latency_us(&self) -> u64
pub fn avg_vector_latency_us(&self) -> u64
Gets the average vector latency in microseconds.
Sourcepub fn avg_graph_latency_us(&self) -> u64
pub fn avg_graph_latency_us(&self) -> u64
Gets the average graph latency in microseconds.
Sourcepub fn vector_query_count(&self) -> u64
pub fn vector_query_count(&self) -> u64
Gets the total number of vector queries.
Sourcepub fn graph_query_count(&self) -> u64
pub fn graph_query_count(&self) -> u64
Gets the total number of graph queries.

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>
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);
