Struct spirit::fragment::driver::Trivial

pub struct Trivial;

A trivial Driver that does no caching at all.

Every time the Driver is called, the resource is created anew and the old one replaced.

fn clone(&self) -> Trivial

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Trivial

impl Debug for Trivial

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for Trivial

fn default() -> Trivial

Returns the "default value" for a type.

impl<F: Fragment> Driver<F> for Trivial

type SubFragment = F

The smaller Fragment the driver cuts F into.

fn instructions<T, I>(
    &mut self,
    fragment: &F,
    transform: &mut T,
    name: &'static str
) -> Result<Vec<Instruction<T::OutputResource>>, Vec<AnyError>> where
    T: Transformation<F::Resource, I, F>, 

Issues the instructions how to transition to the new fragment.

fn confirm(&mut self, _name: &'static str)

Call to this method informs the Driver that the instructions returned by the last call to instructions were followed and the changes have taken place.

fn abort(&mut self, _name: &'static str)

Call to this method informs the Driver that the instructions returned by the last call to instructions were not followed and were dropped.

fn maybe_cached(&self, _: &F, _name: &'static str) -> bool

Informs if there's a chance the new fragment will use something in the Driver's cache if applied.
