Enum ArgPredicate

pub enum ArgPredicate {
    IsPresent,
    Equals(OsStr),
}

Operations to perform on argument values

These do not apply to ValueSource::DefaultValue

Variants

IsPresent

Is the argument present?

Equals(OsStr)

Does the argument match the specified value?

Trait Implementations

impl Clone for ArgPredicate

fn clone(&self) -> ArgPredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgPredicate

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

Formats the value using the given formatter.

impl<S> From<S> for ArgPredicate

where S: Into<OsStr>,

fn from(other: S) -> ArgPredicate

Converts to this type from the input type.

impl PartialEq for ArgPredicate

fn eq(&self, other: &ArgPredicate) -> 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 Eq for ArgPredicate

impl StructuralPartialEq for ArgPredicate

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
