Struct SandboxSpec 

pub struct SandboxSpec {
    pub read_only_paths: Vec<PathBuf>,
    pub writable_paths: Vec<PathBuf>,
    pub network: NetworkPolicy,
    pub env: Vec<(String, String)>,
    pub timeout: Option<Duration>,
}

What a sandboxed command is permitted to touch.

Construct with SandboxSpec::deny_all, then relax. Validation lives in SandboxSpec::validate so an impossible policy is rejected before any process is spawned.

Fields

read_only_paths: Vec<PathBuf>

Paths mounted read-only inside the sandbox.

writable_paths: Vec<PathBuf>

Paths the command may write.

network: NetworkPolicy

Network reachability.

env: Vec<(String, String)>

Environment handed to the command, applied after the backend default.

timeout: Option<Duration>

Wall-clock limit; None means the backend default applies.

Implementations

impl SandboxSpec

pub fn deny_all() -> Self

A policy that grants nothing: no writable paths, no network.

pub fn with_read_only(self, path: impl Into<PathBuf>) -> Self

Grant a read-only path.

pub fn with_writable(self, path: impl Into<PathBuf>) -> Self

Grant a writable path.

pub fn with_network(self, network: NetworkPolicy) -> Self

Set network reachability.

pub fn with_timeout(self, timeout: Duration) -> Self

Set a wall-clock limit.

pub fn validate(&self) -> Result<(), SpecError>

Reject a policy that cannot be enforced.

A path granted both read-only and writable is ambiguous: whether a write lands depends on backend and mount order, so it is refused rather than silently resolved.

Trait Implementations

impl Clone for SandboxSpec

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SandboxSpec

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

impl Default for SandboxSpec

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SandboxSpec
