mutateAsync

boolean

Boolean variables derived from status.

isPaused

boolean

• will be true if the mutation has been paused.

status

'idle' | 'pending' | 'error' | 'success'

• 'idle' initial status prior to the mutation function executing.
• 'pending' if the mutation is currently executing.
• 'error' if the last mutation attempt resulted in an error.
• 'success' if the last mutation attempt was successful.

reset

() => void

A function to clean the mutation internal state (e.g. it resets the mutation to its initial state).
