Expand description

Virtual workspace for devshell: Mode S (memory) or Mode P (guest-primary).

Required Methods§

Source

fn logical_cwd(&self) -> String

Source

fn set_logical_cwd(&mut self, path: &str) -> Result<(), WorkspaceBackendError>

Source

fn read_file(&mut self, path: &str) -> Result<Vec<u8>, WorkspaceBackendError>

Source

fn write_file( &mut self, path: &str, data: &[u8], ) -> Result<(), WorkspaceBackendError>

Source

fn list_dir(&mut self, path: &str) -> Result<Vec<String>, WorkspaceBackendError>

Source

fn mkdir(&mut self, path: &str) -> Result<(), WorkspaceBackendError>

Source

fn remove(&mut self, path: &str) -> Result<(), WorkspaceBackendError>

Source

fn exists(&mut self, path: &str) -> Result<bool, WorkspaceBackendError>

Source

fn try_resolve_guest_path( &self, logical_path: &str, ) -> Result<String, WorkspaceBackendError>

Mode P: logical path → guest absolute path. Mode S: WorkspaceBackendError::ModeSOnly.

Source

fn run_rust_tool( &mut self, vm_session: &mut SessionHolder, program: &str, args: &[String], ) -> Result<ExitStatus, WorkspaceBackendError>

Run rustup / cargo (Mode S: sync VFS↔host/VM). Mode P skeleton: WorkspaceBackendError::Unsupported.
