Enum HandleAvailability 

#[repr(i32)]
pub enum HandleAvailability {
    Unspecified = 0,
    Available = 1,
    Held = 2,
    Taken = 3,
    Reserved = 4,
    Confusable = 5,
}

Availability of a native handle after normalization and classification. RESERVED represents an explicit policy reservation; implementations MUST NOT infer it merely because a name is otherwise unavailable.

Variants

Unspecified = 0

No usable classification was produced. The caller may retry the safe GetHandleStatus read; it MUST NOT infer that a mutation is allowed.

Available = 1

No other-owner hold, active native handle, or confusable collision blocks this caller. held_for_verified_owner = false means a genuinely free name: a new account claims it through BeginWebAuthnRegistration followed by RegisterPublicKey. held_for_verified_owner = true means the caller may own the nonblocking verified-owner hold; ClaimHandle is the authoritative self-claim check.

Held = 2

A verified-owner hold for another subject blocks this caller. The only mutation offered to the caller is RequestHeldName, which starts the right-of-first-refusal window without exposing the owner.

Taken = 3

An active native handle already owns this name. ResolveHandle can read the public subject-free projection; no claim or escrow mutation is available.

Reserved = 4

Explicit policy reservation. No handle mutation is available for this candidate; choose another candidate and call GetHandleStatus again.

Confusable = 5

The candidate conflicts with a trust-bearing handle under the confusable classifier, so no free-name registration mutation is available; choose another candidate and call GetHandleStatus again. ClaimHandle remains only for a previously earned caller-owned verified-owner hold and is the authoritative check for that hidden ownership fact.

Implementations

impl HandleAvailability

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

Returns true if value is a variant of HandleAvailability.

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

👎Deprecated:

Use the TryFrom<i32> implementation instead

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

impl HandleAvailability

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 HandleAvailability

fn clone(&self) -> HandleAvailability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HandleAvailability

impl Debug for HandleAvailability

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

Formats the value using the given formatter.

impl Default for HandleAvailability

fn default() -> HandleAvailability

Returns the “default value” for a type.

impl Eq for HandleAvailability

impl From<HandleAvailability> for i32

fn from(value: HandleAvailability) -> i32

impl Hash for HandleAvailability

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,
