Enum MetadataPolicy 

pub enum MetadataPolicy {
    Base(i32),
    And(Vec<MetadataPolicy>),
    Any(Vec<MetadataPolicy>),
}

A group metadata permission policy, mirroring the wire MetadataPolicy.

Tags stay raw integers so a policy this build does not know survives the trip from the backend to a group registry unchanged.

Variants

Base(i32)

A MetadataBasePolicy tag. 0, unspecified, also stands for a wire policy with no kind set; validation refuses both.

And(Vec<MetadataPolicy>)

Every policy must allow.

Any(Vec<MetadataPolicy>)

At least one policy must allow.

Trait Implementations

impl Clone for MetadataPolicy

fn clone(&self) -> MetadataPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataPolicy

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

Formats the value using the given formatter.

impl PartialEq for MetadataPolicy

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