Enum UseDefault 

pub enum UseDefault {
    Enabled,
    Disabled,
}

Default value for a USE flag that is not defined by the dependency package

When a package does not define a particular USE flag in its IUSE, the default annotation specifies what value the package manager should assume.

See PMS 8.3.4.

Variants

Enabled

(+) — assume the flag is enabled if not defined by the package.

Disabled

(-) — assume the flag is disabled if not defined by the package.

Trait Implementations

impl Clone for UseDefault

fn clone(&self) -> UseDefault

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UseDefault

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

Formats the value using the given formatter.

impl Display for UseDefault

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

Formats the value using the given formatter.

impl Hash for UseDefault

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 PartialEq for UseDefault

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