Enum cfg_expr::expr::Func

pub enum Func {
    Not,
    All,
    Any,
}

A predicate function, used to combine 1 or more predicates into a single value

Variants

Not

not() with a configuration predicate. It is true if its predicate is false and false if its predicate is true.

All

all() with a comma separated list of configuration predicates. It is false if at least one predicate is false. If there are no predicates, it is true.

Any

any() with a comma separated list of configuration predicates. It is true if at least one predicate is true. If there are no predicates, it is false.

Trait Implementations

impl Clone for Func

fn clone(&self) -> Func

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Func

impl Debug for Func

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

Formats the value using the given formatter.

impl Eq for Func

impl Ord for Func

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Func> for Func

fn eq(&self, other: &Func) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<Func> for Func

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

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

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

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

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

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