Enum PollerBehavior 

pub enum PollerBehavior {
    SimpleMaximum(usize),
    Autoscaling {
        minimum: usize,
        maximum: usize,
        initial: usize,
    },
}

Different strategies for task polling

Variants

SimpleMaximum(usize)

Will attempt to poll as long as a slot is available, up to the provided maximum. Cannot be less than two for workflow tasks, or one for other tasks.

Autoscaling

Will automatically scale the number of pollers based on feedback from the server. Still requires a slot to be available before beginning polling.

Fields

minimum: usize

At least this many poll calls will always be attempted (assuming slots are available). Cannot be zero.

maximum: usize

At most this many poll calls will ever be open at once. Must be >= minimum.

initial: usize

This many polls will be attempted initially before scaling kicks in. Must be between minimum and maximum.

Implementations

impl PollerBehavior

pub fn is_autoscaling(&self) -> bool

Returns true if the behavior is using autoscaling.

pub fn validate(&self) -> Result<(), String>

Validates the behavior.

Trait Implementations

impl Clone for PollerBehavior

fn clone(&self) -> PollerBehavior

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PollerBehavior

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PollerBehavior

fn eq(&self, other: &PollerBehavior) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
