Enum Visibility 

pub enum Visibility {
    Private,
    Module,
    Public,
}

How far a type, function or field can be seen from.

Ordered from narrowest to widest, so a wider visibility satisfies a narrower requirement. See Visibility::is_visible.

Variants

Private

Visible only inside the type that declares it.

Module

Visible inside the declaring module.

Public

Visible everywhere. The default.

Implementations

impl Visibility

pub fn is_visible(self, scope: Visibility) -> bool

Returns true when this visibility is at least as wide as scope.

assert!(Visibility::Public.is_visible(Visibility::Module));
assert!(!Visibility::Private.is_visible(Visibility::Module));

pub fn is_public(&self) -> bool

Returns true for Visibility::Public.

pub fn is_module(&self) -> bool

Returns true for Visibility::Module.

pub fn is_private(&self) -> bool

Returns true for Visibility::Private.

Trait Implementations

impl Clone for Visibility

fn clone(&self) -> Visibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Visibility

impl Debug for Visibility

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

Formats the value using the given formatter.

impl Default for Visibility

fn default() -> Visibility

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Visibility

fn deserialize<__D>( __deserializer: __D, ) -> Result<Visibility, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Visibility

impl Hash for Visibility

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Visibility

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Visibility

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Visibility

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

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

impl Serialize for Visibility

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
