Enum Visibility 

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

Unified three-tier visibility for both spool EXISTENCE (visibility) and spool HISTORY (state_visibility). One type, one numbering.

Canonical numbering is restrictiveness order (narrowest first): PRIVATE = 1, INTERNAL = 2, PUBLIC = 3

This replaces the former SpoolVisibility {PRIVATE=1, PUBLIC=2} and SpoolStateVisibility {PUBLIC=1, INTERNAL=2, PRIVATE=3}. Those two enums were differently numbered; a numeric cast between them published private history as public. Consumers MUST map by variant NAME, never by discriminant. Retired type names are not reused.

Tiers: PRIVATE — scoped to the owning user / explicit grant holders. INTERNAL — scoped to members of the containing org/team spool. Expressible for existence only on org- or team-parented spools; rejected for user-parented and root-level (__users / __orgs) spools. PUBLIC — everyone, including anonymous.

Coherence: PUBLIC history requires PUBLIC existence. A PRIVATE spool with INTERNAL history is the default (same grant-holder set) and is legal. There is no “signed-in Heddle users only” tier.

Variants

Unspecified = 0

Private = 1

Internal = 2

Public = 3

Implementations

impl Visibility

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

Returns true if value is a variant of Visibility.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl Visibility

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<Self>

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

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

Formats the value using the given formatter.

impl Default for Visibility

fn default() -> Visibility

Returns the “default value” for a type.

impl Eq for Visibility

impl From<Visibility> for i32

fn from(value: Visibility) -> i32

Converts to this type from the input type.

impl Hash for Visibility

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 Ord for Visibility

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

This method returns an Ordering between self and other.

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.

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 Visibility

impl TryFrom<i32> for Visibility

type Error = UnknownEnumValue
