Enum Predicate

pub enum Predicate {
    Any(Vec<Box<Predicate>>),
    All(Vec<Box<Predicate>>),
    Not(Box<Predicate>),
    Name(String),
    NameValue(String, String),
}

A configuration predicate.

Variants

Any(Vec<Box<Predicate>>)

A configuration predicate success when any of sub-predicates success.

All(Vec<Box<Predicate>>)

A configuration predicate success when all of sub-predicates success.

Not(Box<Predicate>)

A configuration predicate apply not operator to a predicate.

Name(String)

A configuration predicate with name.

NameValue(String, String)

A configuration predicate with name and value.

Implementations

impl Predicate

pub fn matches<P: Pattern>(&self, pattern: &P) -> bool

Returns true if configuration matches the predicate

Trait Implementations

impl AsMut<Predicate> for Cfg

fn as_mut(&mut self) -> &mut Predicate

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Predicate> for Cfg

fn as_ref(&self) -> &Predicate

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl Display for Predicate

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

Formats the value using the given formatter.

impl From<Cfg> for Predicate

fn from(cfg: Cfg) -> Self

Converts to this type from the input type.

impl From<Predicate> for Cfg

fn from(predicate: Predicate) -> Self

Converts to this type from the input type.

impl Hash for Predicate

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 Predicate

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