Trait FileStore 

pub trait FileStore: Send + Sync {
    // Required methods
    fn read(&self, path: &Path) -> Result<String, GettextError>;
    fn write(&self, path: &Path, content: &str) -> Result<(), GettextError>;
    fn modified_time(&self, path: &Path) -> Result<SystemTime, GettextError>;
    fn exists(&self, path: &Path) -> bool;

    // Provided method
    fn write_bytes(&self, path: &Path, bytes: &[u8]) -> Result<(), GettextError> { ... }
}

File I/O contract used by crate::service::store::GettextStore.

Implementations are expected to be Send + Sync so they can be shared behind an Arc across async tasks. Reads and writes are blocking by design (called from spawn_blocking in the store layer).

Required Methods

fn read(&self, path: &Path) -> Result<String, GettextError>

Read the file at path as a UTF-8 string. Implementations should strip any leading UTF-8 BOM before returning.

fn write(&self, path: &Path, content: &str) -> Result<(), GettextError>

Atomically write content to path. Implementations should hold an advisory lock on the target during the write where possible.

fn modified_time(&self, path: &Path) -> Result<SystemTime, GettextError>

Return the on-disk modified time of path, used by the store manager to detect external edits and invalidate caches.

fn exists(&self, path: &Path) -> bool

true if path exists on disk.

Provided Methods

fn write_bytes(&self, path: &Path, bytes: &[u8]) -> Result<(), GettextError>

Atomically write a raw byte buffer to path. Used for binary artifacts like .mo files. Default impl just routes through FileStore::write by treating the bytes as UTF-8 — implementors that need to honour arbitrary bytes (the production FsFileStore) should override.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
