Struct MobileCounterStore 

pub struct MobileCounterStore { /* private fields */ }

Durable adapter used by the iOS umsh_hal::CounterStore boundary.

Each commit writes and synchronizes a temporary record, atomically renames it over the previous boundary, then synchronizes the containing directory. An error at any stage is treated as ambiguous by the caller and therefore cannot release a prepared authenticated frame for transmission.

Implementations

impl MobileCounterStore

pub fn new(root_directory: String) -> Result<Arc<Self>, CounterStoreError>

pub fn load_boundary(&self, context: Vec<u8>) -> Result<u32, CounterStoreError>

pub fn commit_boundary( &self, context: Vec<u8>, boundary: u32, ) -> Result<(), CounterStoreError>
