Struct PluginFileSystem 

pub struct PluginFileSystem { /* private fields */ }

An AsyncFileSystem backed by an Extism storage plugin.

All trait methods dispatch to plugin commands (ReadFile, WriteFile, etc.) and parse the JSON response.

Trait Implementations

impl AsyncFileSystem for PluginFileSystem

fn read_to_string<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Result<String>>

Reads the file content as a string.

fn write_file<'a>( &'a self, path: &'a Path, content: &'a str, ) -> BoxFuture<'a, Result<()>>

Overwrites an existing file with new content.

fn create_new<'a>( &'a self, path: &'a Path, content: &'a str, ) -> BoxFuture<'a, Result<()>>

Creates a file ONLY if it doesn’t exist. Should return an error if file exists.

fn delete_file<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Result<()>>

Deletes a file.

fn list_md_files<'a>( &'a self, dir: &'a Path, ) -> BoxFuture<'a, Result<Vec<PathBuf>>>

Finds markdown files in a folder.

fn exists<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, bool>

Checks if a file or directory exists.

fn create_dir_all<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Result<()>>

Creates a directory and all parent directories.

fn is_dir<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, bool>

Checks if a path is a directory.

fn move_file<'a>( &'a self, from: &'a Path, to: &'a Path, ) -> BoxFuture<'a, Result<()>>

Move/rename a file from from to to.

fn read_binary<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Result<Vec<u8>>>

Read binary file content.

fn hash_file<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Result<String>>

Compute the SHA-256 hash of a file and return it as lowercase hex.

fn write_binary<'a>( &'a self, path: &'a Path, content: &'a [u8], ) -> BoxFuture<'a, Result<()>>

Write binary content to a file.

fn list_files<'a>( &'a self, dir: &'a Path, ) -> BoxFuture<'a, Result<Vec<PathBuf>>>

List all files in a directory (not recursive).

fn get_modified_time<'a>(&'a self, path: &'a Path) -> BoxFuture<'a, Option<i64>>

Get file modification time as milliseconds since Unix epoch.

fn is_symlink<'a>( &'a self, _path: &'a Path, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'a>>

Checks if a path is a symlink. Returns false for non-existent paths or on platforms that don’t support symlinks.

fn clear_dir<'a>( &'a self, dir: &'a Path, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'a>>

Delete all files and subdirectories within a directory. The directory itself is preserved (remains as an empty directory).

fn list_md_files_recursive<'a>( &'a self, dir: &'a Path, ) -> Pin<Box<dyn Future<Output = Result<Vec<PathBuf>, Error>> + Send + 'a>>

Recursively list all markdown files in a directory and its subdirectories.

fn list_all_files_recursive<'a>( &'a self, dir: &'a Path, ) -> Pin<Box<dyn Future<Output = Result<Vec<PathBuf>, Error>> + Send + 'a>>

Recursively list ALL files and directories in a directory.

fn get_file_size<'a>( &'a self, _path: &'a Path, ) -> Pin<Box<dyn Future<Output = Option<u64>> + Send + 'a>>

Get file size in bytes.

fn mark_sync_write_start(&self, _path: &Path)

Mark a path as being written from sync (skip CRDT updates if applicable).

fn mark_sync_write_end(&self, _path: &Path)

Clear the sync write marker for a path.
