pub struct TokenBucket { /* private fields */ }Expand description
Token bucket rate limiter.
Maintains a token pool that refills at a constant rate and depletes by one token per request. Burst capacity limits the maximum token accumulation.
Implementations§
Source§impl TokenBucket
impl TokenBucket
Sourcepub fn new(refill_rate: f64, burst_capacity: u32) -> Self
pub fn new(refill_rate: f64, burst_capacity: u32) -> Self
Creates a new token bucket.
§Arguments
refill_rate: Tokens added per second.burst_capacity: Maximum tokens the bucket can hold.
§Returns
Returns a fully filled TokenBucket.
Sourcepub fn from_config(config: &RateLimitConfig) -> Self
pub fn from_config(config: &RateLimitConfig) -> Self
Creates a token bucket from rate limit configuration.
§Arguments
config: Rate limit configuration.
§Returns
Returns a configured TokenBucket.
Sourcepub fn try_consume(&mut self) -> bool
pub fn try_consume(&mut self) -> bool
Attempts to consume one token.
§Returns
Returns true if a token was available and consumed, false if
the bucket is empty.
Sourcepub fn check_rate_limit(
&mut self,
config: &RateLimitConfig,
) -> Result<(), DashboardError>
pub fn check_rate_limit( &mut self, config: &RateLimitConfig, ) -> Result<(), DashboardError>

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>
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);
