Struct PursuitChanged 

pub struct PursuitChanged {
    pub step: PursuitMove,
    pub goal: Option<String>,
}

pursuit_changed: one step a person took on a building’s pursuit, and the goal the building holds after it.

goal is absent exactly when the step left no pursuit, which is a clear; every other step leaves one and writes its goal.

Fields

step: PursuitMove

goal: Option<String>

Implementations

impl PursuitChanged

pub fn held(self) -> Result<Option<(String, PursuitState)>, AxError>

The goal and state the building holds after this step, or None when the step cleared it.

Errors

Refuses a step that leaves a pursuit but names no goal: a reader that invented an empty goal for it would hold a pursuit nobody declared.
