pub struct Scheduler { /* private fields */ }Expand description
The cron scheduler. Runs registered tasks on their configured schedules.
Implementations§
Source§impl Scheduler
impl Scheduler
pub fn new(job_queue: Arc<JobQueue>) -> Self
Sourcepub fn schedule(
&self,
name: &str,
cron_expr: &str,
handler: JobHandler,
) -> Result<(), String>
pub fn schedule( &self, name: &str, cron_expr: &str, handler: JobHandler, ) -> Result<(), String>
Register a cron task. The handler will also be registered with the job queue so that workers can execute it.
Sourcepub fn start(self: Arc<Self>) -> SchedulerHandle
pub fn start(self: Arc<Self>) -> SchedulerHandle
Start the scheduler loop in a background thread.
Sourcepub fn tick(&self)
pub fn tick(&self)
Check all tasks and enqueue any that match the current time.
This is also useful for testing: call tick() directly to simulate
the scheduler loop without waiting for the background thread.
Sourcepub fn list_tasks(&self) -> Vec<TaskInfo>
pub fn list_tasks(&self) -> Vec<TaskInfo>
List all scheduled tasks.
Sourcepub fn set_enabled(&self, name: &str, enabled: bool) -> bool
pub fn set_enabled(&self, name: &str, enabled: bool) -> bool
Enable or disable a task by name. Returns true if the task was found.

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().

painted.white();Source§fn bright_black(&self) -> 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.

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);
