Struct FileStore 

pub struct FileStore { /* private fields */ }

Debug prints the root only: a store handle appears in test assertions and in error context, and the lock’s file descriptor is noise there.

Implementations

impl FileStore

pub fn open(root: &Path) -> Result<FileStore, StoreError>

Open root, creating it, and take the exclusive instance lock.

pub fn root(&self) -> &Path

Trait Implementations

impl Debug for FileStore

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

Formats the value using the given formatter.

impl Store for FileStore

fn put( &self, key: &str, seq: u64, envelope: &Value, ) -> Result<PutOutcome, StoreError>

Compare-and-set write: seq must exceed the stored one.

fn get(&self, key: &str, _seq: Option<u64>) -> Result<Option<Value>, StoreError>

The latest record (or the pinned seq if the store keeps history).

fn list(&self, prefix: &str) -> Result<Vec<KeySeq>, StoreError>

Keys under prefix (optional; Unsupported is a legal answer).

fn delete(&self, key: &str) -> Result<(), StoreError>

Remove a key (optional; Unsupported ⇒ callers tombstone via put).

fn kind(&self) -> &'static str

The adapter kind (mcp / http / file / memory), for status and metrics.
