Struct Visibility 

#[non_exhaustive]
pub struct Visibility {
    pub rules: Vec<VisibilityRule>,
    /* private fields */
}

Visibility restricts service consumer’s access to service elements, such as whether an application can call a visibility-restricted method. The restriction is expressed by applying visibility labels on service elements. The visibility labels are elsewhere linked to service consumers.

A service can define multiple visibility labels, but a service consumer should be granted at most one visibility label. Multiple visibility labels for a single service consumer are not supported.

If an element and all its parents have no visibility label, its visibility is unconditionally granted.

Example:

visibility:
  rules:
  - selector: google.calendar.Calendar.EnhancedSearch
    restriction: PREVIEW
  - selector: google.calendar.Calendar.Delegate
    restriction: INTERNAL

Here, all methods are publicly visible except for the restricted methods EnhancedSearch and Delegate.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

rules: Vec<VisibilityRule>

A list of visibility rules that apply to individual API elements.

NOTE: All service configuration rules follow “last one wins” order.

Implementations

impl Visibility

pub fn new() -> Self

pub fn set_rules<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<VisibilityRule>,

Sets the value of rules.

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 Debug for Visibility

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

Formats the value using the given formatter.

impl Default for Visibility

fn default() -> Visibility

Returns the “default value” for a type.

impl Message for Visibility

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Visibility

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