Enum ProcessSandboxPreset 

pub enum ProcessSandboxPreset {
    SystemRuntime,
    DeveloperToolchains,
    PackageManagerConfig,
    UserTemp,
}

Named host filesystem presets granted only to child-process OS sandboxes. These do not widen Harn file builtins; they are used so subprocesses can load runtimes, compilers, and cache files that live outside the workspace while Harn’s own read/write surface remains scoped by workspace_roots and read_only_roots.

Variants

SystemRuntime

Minimal host runtime roots needed to execute common system binaries.

DeveloperToolchains

OS/vendor developer toolchains such as Xcode, Command Line Tools, Homebrew, plus common user-managed runtime roots such as ~/.local/share/uv, ~/.rustup, ~/.cargo, ~/.pyenv, and ~/.nvm.

PackageManagerConfig

Per-user package-manager config/cache roots used by npm, pip, cargo, git credential helpers, and enterprise CA configuration.

UserTemp

Per-user scratch/cache locations used by developer tools. Write access is granted only when the active policy already allows workspace writes.

Implementations

Trait Implementations

impl Clone for ProcessSandboxPreset

fn clone(&self) -> ProcessSandboxPreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProcessSandboxPreset

impl Debug for ProcessSandboxPreset

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProcessSandboxPreset

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Eq for ProcessSandboxPreset

impl Hash for ProcessSandboxPreset

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ProcessSandboxPreset

fn cmp(&self, other: &ProcessSandboxPreset) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ProcessSandboxPreset

fn eq(&self, other: &ProcessSandboxPreset) -> 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.

impl PartialOrd for ProcessSandboxPreset

fn partial_cmp(&self, other: &ProcessSandboxPreset) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ProcessSandboxPreset

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
