Struct PresetStateStore 

pub struct PresetStateStore { /* private fields */ }

Manages per-preset state and generates recall MIDI on switch.

Implementations

impl PresetStateStore

pub fn new() -> Self

pub fn current(&self) -> &PresetState

Get a reference to the current active preset’s state.

pub fn current_mut(&mut self) -> &mut PresetState

Get a mutable reference to the current active preset’s state.

pub fn active_index(&self) -> u8

Current active preset index.

pub fn save_working(&mut self, working: &PresetState)

Save working state into the active preset slot (for serialization without switching).

pub fn clear(&mut self)

Reset all state (presets changed, state is stale).

pub fn set_state(&mut self, index: usize, state: PresetState)

Set state for a specific preset slot.

pub fn apply_defaults(&mut self, presets: &[&Preset])

Reset state using preset defaults (after upload / first boot). Each preset’s declared initial state is applied.

pub fn cleared_eeprom() -> [u8; 128]

Return a cleared EEPROM buffer (for writing after preset upload).

pub fn switch( &mut self, new_preset: u8, working: &mut PresetState, preset: &Preset, ) -> Vec<MidiMessage, 16>

Switch to a new preset. Saves current working state, loads new state, and returns MIDI messages to recall the new preset’s state to external gear.

impl PresetStateStore

pub fn to_eeprom(&self, buf: &mut [u8; 128])

Serialize entire store to EEPROM buffer (128 bytes). Layout: [magic][active_preset][state0..stateN]

pub fn from_eeprom(buf: &[u8; 128]) -> Option<Self>

Deserialize from EEPROM buffer. Returns None if magic/version doesn’t match.

Trait Implementations

impl Clone for PresetStateStore

fn clone(&self) -> PresetStateStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for PresetStateStore

fn default() -> Self

Returns the “default value” for a type.
