Rush to frustrate (4)

I believe the answer is:

dash

This clue is a double definition.

'rush' is the first definition.
(I know that dash is a type of rush)

'to frustrate' is the second definition.
(I know this)

(Other definitions for dash that I've seen before include "Stylish vigour; frustrate (hopes)" , "Rush - elan" , "Run fast with flair" , "instrument panel" , "gratuity" .)

I've seen this clue in The Irish Independent.
