Enum EnvChange

pub enum EnvChange {
    Remove,
    Set(OsString),
    Inherit,
}

Used to determine how a env variable should be updated.

Variants

Remove

Remove the env value if it normally would have been set

(e.g. because of inherited environment)

Set(OsString)

Make sure the env variable will have given value in the sub-process.

Inherit

Make sure the env variable is inherited from the process spawning the sub-process.

If environment inheritance is disabled (e.g. using with_inherit_env(false)) this will cause given values to still be inherited anyway.

If environment inheritance is enabled this won’t have any effect.

Trait Implementations

impl Clone for EnvChange

fn clone(&self) -> EnvChange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnvChange

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

Formats the value using the given formatter.

impl From<&EnvChange> for EnvChange

fn from(borrow: &Self) -> Self

Converts to this type from the input type.

impl From<&OsStr> for EnvChange

fn from(val: &OsStr) -> Self

Converts to this type from the input type.

impl From<&OsString> for EnvChange

fn from(val: &OsString) -> Self

Converts to this type from the input type.

impl From<&str> for EnvChange

fn from(val: &str) -> Self

Converts to this type from the input type.

impl From<OsString> for EnvChange

fn from(val: OsString) -> Self

Converts to this type from the input type.

impl From<String> for EnvChange

fn from(val: String) -> Self

impl PartialEq for EnvChange

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