ActionContext

Struct ActionContext 

Source
pub struct ActionContext<'a> {
    pub data: Option<&'a Value>,
    pub me: Option<&'a str>,
    pub now: Option<f64>,
    pub offset: Option<&'a (dyn Fn(f64) -> i32 + Send + Sync)>,
    pub max_steps: Option<usize>,
}
Expand description

The snapshot an action runs against.

Fields§

§data: Option<&'a Value>

The surface data model at the press (the data var; None = null).

§me: Option<&'a str>

The member pressing (the me var; None = null).

§now: Option<f64>

The clock (epoch ms; None = the wall clock).

§offset: Option<&'a (dyn Fn(f64) -> i32 + Send + Sync)>

The team zone: minutes east of UTC at an instant (None = UTC).

§max_steps: Option<usize>

The run’s evaluation budget (default ACTION_LIMIT_MAX_STEPS).
