Struct VmConfig 

pub struct VmConfig {
    pub enabled: bool,
    pub backend: String,
    pub eager_start: bool,
    pub lima_instance: String,
}

Parsed VM-related environment.

Fields

enabled: bool

DEVSHELL_VM enabled.

backend: String

Raw backend string (trimmed); see ENV_DEVSHELL_VM_BACKEND for defaults.

eager_start: bool

Eager VM/session start when REPL opens (vs lazy on first rustup/cargo).

lima_instance: String

Lima instance name.

Implementations

impl VmConfig

pub fn from_env() -> Self

Read configuration from process environment.

pub const fn disabled() -> Self

Config with VM mode off (for tests).

pub fn use_host_sandbox(&self) -> bool

Normalized backend: host and auto use the host temp sandbox; lima uses γ (Unix; see docs/devshell-vm-gamma.md).

pub fn workspace_mode_effective(&self) -> WorkspaceMode

Effective workspace mode after combining workspace_mode_from_env with VM availability (guest-primary design §6).

Returns WorkspaceMode::Guest only when the user requested guest, VmConfig::enabled is true, VmConfig::use_host_sandbox is false, and the backend is lima or beta. Otherwise returns WorkspaceMode::Sync without erroring.

Trait Implementations

impl Clone for VmConfig

fn clone(&self) -> VmConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VmConfig

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

Formats the value using the given formatter.

impl PartialEq for VmConfig

fn eq(&self, other: &VmConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
