Implementations§
Source§impl ThompsonSampling
impl ThompsonSampling
Sourcepub fn add_variant(&mut self, variant_id: Uuid)
pub fn add_variant(&mut self, variant_id: Uuid)
Add a new variant
Sourcepub fn remove_variant(&mut self, variant_id: &Uuid)
pub fn remove_variant(&mut self, variant_id: &Uuid)
Remove a variant
Sourcepub fn select_variant(&self) -> Result<Uuid>
pub fn select_variant(&self) -> Result<Uuid>
Select a variant using Thompson Sampling
This samples from each arm’s Beta distribution and selects the arm with the highest sampled value.
Sourcepub fn update(&mut self, variant_id: &Uuid, success: bool) -> Result<()>
pub fn update(&mut self, variant_id: &Uuid, success: bool) -> Result<()>
Update a variant with observation
Sourcepub fn get_conversion_rates(&self) -> HashMap<Uuid, f64>
pub fn get_conversion_rates(&self) -> HashMap<Uuid, f64>
Get current conversion rates for all variants
Sourcepub fn calculate_regret(&self) -> f64
pub fn calculate_regret(&self) -> f64
Calculate regret (difference from optimal arm)
Sourcepub fn total_samples(&self) -> u64
pub fn total_samples(&self) -> u64
Get total number of samples
Sourcepub fn has_converged(&self, threshold: f64) -> bool
pub fn has_converged(&self, threshold: f64) -> bool
Check if bandit has converged (low regret relative to samples)

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.

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<SS, SP> SupersetOf<SS> for SPwhere
