Enum EnvScope 

#[non_exhaustive]
pub enum EnvScope {
    User,
    Machine,
    Session,
}

Environment-variable persistence scope.

Marked #[non_exhaustive] so future scopes (e.g. per-shell rc-file, systemd user-session) can land without breaking external match sites.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

User

Current user (HKCU / shell rc). Default.

Machine

System-wide (HKLM / /etc/environment). Needs admin.

Session

Current process only.

Trait Implementations

impl Clone for EnvScope

fn clone(&self) -> EnvScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnvScope

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

Formats the value using the given formatter.

impl Default for EnvScope

fn default() -> EnvScope

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for EnvScope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EnvScope

fn eq(&self, other: &EnvScope) -> 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 Serialize for EnvScope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for EnvScope

impl Eq for EnvScope

impl StructuralPartialEq for EnvScope
