Enum QuotaScope 

#[non_exhaustive]
pub enum QuotaScope {
    Account,
    Domain,
    Global,
    Other(String),
}

RFC 9425 §3.1 Scope — the set of accounts the quota limit applies to.

Wire strings: "account", "domain", "global". Other(String) preserves any unrecognized value for lossless round-trip.

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.

Account

Quota applies to this account only.

Domain

Quota applies to all accounts sharing this domain.

Global

Quota applies to all accounts on the server.

Other(String)

Catch-all for any unrecognized wire value from a future spec version. The original wire value is preserved for lossless round-trip.

Forging caveat

Other(String) is pub, so callers can construct QuotaScope::Other("account".into()). The custom serde impl emits the wrapped string verbatim on serialize and normalises canonical wire strings to their typed variant on deserialize. Consequences:

• QuotaScope::Other("account".into()) != QuotaScope::Account on PartialEq, but both serialize to "account".
• Other("account") -> "account" -> Account is a lossy round-trip (the variant changes shape).

Reserve Other(s) for genuinely unrecognised wire strings. Comparing wire-string equality across two values requires matching on as_str(), not on PartialEq.

Implementations

impl QuotaScope

pub fn as_str(&self) -> &str

The canonical wire string for this quota scope.

Trait Implementations

impl Clone for QuotaScope

fn clone(&self) -> QuotaScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuotaScope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QuotaScope

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for QuotaScope

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

Formats the value using the given formatter.

impl Eq for QuotaScope

impl PartialEq for QuotaScope

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

impl Serialize for QuotaScope

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
