Enum SuccessCondition 

pub enum SuccessCondition {
    TextChanged,
    TextContains(String),
    TextNotContains(String),
    TextEquals(String),
    ManualAdvance,
}

How the tutor decides an exercise is complete.

Variants

TextChanged

Any edit to the anchor line counts as success.

TextContains(String)

The anchor line must now contain this substring.

TextNotContains(String)

The anchor line must no longer contain this substring.

TextEquals(String)

The anchor line must equal this string exactly.

ManualAdvance

Observational exercise: the user must run :tutor-next explicitly. is_met always returns false; the action handler bypasses it.

Implementations

impl SuccessCondition

pub fn is_met(&self, initial: &str, current: &str) -> bool
