Abstract Value Members
- abstract def focus(input: I): Result[O]
Apply the current cursor to the specified input of type
I
.Apply the current cursor to the specified input of type
I
. This allows to select a precise part of the inputI
tree.The method is pure and return a
Left
when the focusing fails- input
target of the cursor
- returns
Right
