Member Function Documentation

clear()

void pulp::view::ABCompare::clear ( Slot slot )

inline

Drop any saved snapshot from slot.

copy()

void pulp::view::ABCompare::copy ( Slot src, Slot dst )

inline

Overwrite dst with a copy of src's snapshot.

Useful when a user wants "start B from A and tweak".

current()

Slot pulp::view::ABCompare::current ( ) const

inline

Which slot is currently live (i.e.

what the StateStore was last switched to). Defaults to A.

has()

bool pulp::view::ABCompare::has ( Slot slot ) const

inline

Does slot currently hold a snapshot?

load_from()

bool pulp::view::ABCompare::load_from ( Slot slot )

inline

Restore the StateStore from slot.

Call once at startup to prime an initial snapshot before any user edits; subsequent load_from calls drive the A/B toggle itself.

save_to()

void pulp::view::ABCompare::save_to ( Slot slot )

inline

Capture the StateStore's current state into slot.

snapshot()

std::span< const uint8_t > pulp::view::ABCompare::snapshot ( Slot slot ) const

inline

Raw snapshot bytes (exposed for serialization of the A/B pair itself — e.g.

persisting A/B across session reloads).

swap()

void pulp::view::ABCompare::swap ( )

inline

Swap A and B.

toggle()

bool pulp::view::ABCompare::toggle ( )

inline

Toggle between A and B. Fails if the target slot has no snapshot.
