Enum Audience 

#[repr(i32)]
pub enum Audience {
    Unspecified = 0,
    Private = 1,
    Members = 2,
    Public = 3,
}

Existence/history audience for a spool. Numeric tags match v1 Visibility (PRIVATE=1, INTERNAL/MEMBERS=2, PUBLIC=3). Do not add AUDIENCE_INTERNAL.

AUDIENCE_MEMBERS — principals who hold a GrantRecord or MemberRecord on this spool, or a GrantRecord on an ancestor with include_descendants=true that reaches this spool (unexpired), or an unrevoked native_support_access row on this spool or on such an ancestor. It is not “any signed-in Heddle user” and is not keyed on parent kind. CreateSpool / ReviseSpool do not reject MEMBERS by parent kind. An ancestor grant with include_descendants=false does not admit a child. Persistence may store the token “internal”; a later rename to “members” is not a widening.

Coherence: default_state_audience <= audience. No PRIVATE-existence + MEMBERS-history carve-out. PUBLIC history requires PUBLIC existence. Discriminant order is restrictiveness: PRIVATE < MEMBERS < PUBLIC.

An owner-signed max_audience ceiling cannot widen this table; it only stops delegated writes from moving this spool or a descendant to a wider cell. See SignedSpoolPolicy.max_audience.

Implementations

impl Audience

pub const fn is_valid(value: i32) -> bool

Returns true if value is a variant of Audience.

pub fn from_i32(value: i32) -> Option<Audience>

👎Deprecated:

Use the TryFrom<i32> implementation instead

Converts an i32 to a Audience, or None if value is not a valid variant.

impl Audience

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Audience>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for Audience

fn clone(&self) -> Audience

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Audience

impl Debug for Audience

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

Formats the value using the given formatter.

impl Default for Audience

fn default() -> Audience

Returns the “default value” for a type.

impl Eq for Audience

impl Hash for Audience

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,

Feeds a slice of this type into the given Hasher.

impl Ord for Audience

fn cmp(&self, other: &Audience) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Audience

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Audience

fn partial_cmp(&self, other: &Audience) -> 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 StructuralPartialEq for Audience
