Enum SessionHolder 

pub enum SessionHolder {
    Host(HostSandboxSession),
    Gamma(GammaSession),
}

Active VM / sandbox backend for one REPL or script run.

Variants

Host(HostSandboxSession)

Gamma(GammaSession)

γ: Lima + host workspace sync (Unix only).

Implementations

impl SessionHolder

pub fn try_from_config(config: &VmConfig) -> Result<Self, VmError>

Build session from config.

Errors

On Unix, DEVSHELL_VM_BACKEND=lima uses GammaSession; fails with VmError::Lima if limactl is missing. On non-Unix, lima returns VmError::BackendNotImplemented.

pub fn new_host() -> Self

Host sandbox only (tests and callers that do not read VmConfig).

pub fn ensure_ready(&mut self, vfs: &Vfs, vfs_cwd: &str) -> Result<(), VmError>

pub fn run_rust_tool( &mut self, vfs: &mut Vfs, vfs_cwd: &str, program: &str, args: &[String], ) -> Result<ExitStatus, VmError>

pub fn shutdown(&mut self, vfs: &mut Vfs, vfs_cwd: &str) -> Result<(), VmError>
