Struct OptionLambda 

Source 
pub struct OptionLambda<A: IVm>(/* private fields */);
Expand description

A region is open and no receiver is live: the state after a ?.() node, a?.(...b), or a |() or |?.() step inside a region. Its steps are |() (call) and |. (dot); no |?.(), and no |!() — there is no receiver for either to justify.

Implementations§

Source§

impl<A: IVm> OptionLambda<A>

Source

pub fn end(self) -> Result<Any<A>, Any<A>>

No continuation: the region closes, a skipped chain is undefined.

Source

pub fn call( self, args: impl FnOnce() -> Result<Any<A>, Any<A>>, ) -> OptionLambda<A>

|(): call the current value, inside the region.

Source

pub fn dot( self, key: impl FnOnce() -> Result<Any<A>, Any<A>>, ) -> OptionPropertyLambda<A>

|.: a property of the current value, inside the region; the value becomes the receiver.
