Enum ServiceState 

#[non_exhaustive]
pub enum ServiceState {
    Init,
    Probing(u8),
    Announcing(u8),
    Established,
    Conflicting,
}

Lifecycle state of a registered service.

Transitions: Init → Probing(0..3) → Announcing(0..2) → Established Probing(_) -[conflict]→ Conflicting (caller decides next step)

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Init

Just registered; waiting on initial 0–250 ms randomized delay.

Probing(u8)

Probing: probes sent so far (0, 1, or 2 — third probe ends probing).

Announcing(u8)

Announcing: announcements sent so far (0 or 1).

Established

Established and serving questions; periodically re-announces.

Conflicting

Detected a conflict while probing; caller must rename and restart.

Implementations

impl ServiceState

pub const fn is_init(&self) -> bool

Returns true if this value is of type Init. Returns false otherwise

pub const fn is_probing(&self) -> bool

Returns true if this value is of type Probing. Returns false otherwise

pub const fn is_announcing(&self) -> bool

Returns true if this value is of type Announcing. Returns false otherwise

pub const fn is_established(&self) -> bool

Returns true if this value is of type Established. Returns false otherwise

pub const fn is_conflicting(&self) -> bool

Returns true if this value is of type Conflicting. Returns false otherwise

impl ServiceState

pub fn unwrap_init(self)

Unwraps this value to the ServiceState::Init variant. Panics if this value is of any other type.

pub fn unwrap_probing(self) -> u8

Unwraps this value to the ServiceState::Probing variant. Panics if this value is of any other type.

pub fn unwrap_announcing(self) -> u8

Unwraps this value to the ServiceState::Announcing variant. Panics if this value is of any other type.

pub fn unwrap_established(self)

Unwraps this value to the ServiceState::Established variant. Panics if this value is of any other type.

pub fn unwrap_conflicting(self)

Unwraps this value to the ServiceState::Conflicting variant. Panics if this value is of any other type.

impl ServiceState

pub fn try_unwrap_init(self) -> Result<(), TryUnwrapError<Self>>

Attempts to unwrap this value to the ServiceState::Init variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_probing(self) -> Result<u8, TryUnwrapError<Self>>

Attempts to unwrap this value to the ServiceState::Probing variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_announcing(self) -> Result<u8, TryUnwrapError<Self>>

Attempts to unwrap this value to the ServiceState::Announcing variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_established(self) -> Result<(), TryUnwrapError<Self>>

Attempts to unwrap this value to the ServiceState::Established variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_conflicting(self) -> Result<(), TryUnwrapError<Self>>

Attempts to unwrap this value to the ServiceState::Conflicting variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

impl ServiceState

pub fn as_str(&self) -> &str

Canonical lowercase slug for this state.

Trait Implementations

impl Clone for ServiceState

fn clone(&self) -> ServiceState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ServiceState

impl Debug for ServiceState

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

Formats the value using the given formatter.

impl Display for ServiceState

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

Formats the value using the given formatter.

impl Eq for ServiceState

impl Hash for ServiceState

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 PartialEq for ServiceState

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