Struct MatchCase 

Source 
pub struct MatchCase<'a> {
    pub pattern: Arc<dyn Shape>,
    pub guard: Option<&'a mut (dyn FnMut(&mut Cx, &ShapeBindings) -> Result<bool> + 'a)>,
}
Expand description

One ordered Python structural-match case composed from a canonical Shape.

Fields§

§pattern: Arc<dyn Shape>

Shape/pattern that performs structural checking and captures.

§guard: Option<&'a mut (dyn FnMut(&mut Cx, &ShapeBindings) -> Result<bool> + 'a)>

Optional guard evaluated only after this pattern accepts.
