Struct QuotaMode

pub struct QuotaMode(/* private fields */);

Supported quota modes.

Implementations

impl QuotaMode

pub const UNSPECIFIED: QuotaMode

Guard against implicit default. Must not be used.

pub const NORMAL: QuotaMode

For AllocateQuota request, allocates quota for the amount specified in the service configuration or specified using the quota metrics. If the amount is higher than the available quota, allocation error will be returned and no quota will be allocated. If multiple quotas are part of the request, and one fails, none of the quotas are allocated or released.

pub const BEST_EFFORT: QuotaMode

The operation allocates quota for the amount specified in the service configuration or specified using the quota metrics. If the amount is higher than the available quota, request does not fail but all available quota will be allocated. For rate quota, BEST_EFFORT will continue to deduct from other groups even if one does not have enough quota. For allocation, it will find the minimum available amount across all groups and deduct that amount from all the affected groups.

pub const CHECK_ONLY: QuotaMode

For AllocateQuota request, only checks if there is enough quota available and does not change the available quota. No lock is placed on the available quota either.

pub const QUERY_ONLY: QuotaMode

Unimplemented. When used in AllocateQuotaRequest, this returns the effective quota limit(s) in the response, and no quota check will be performed. Not supported for other requests, and even for AllocateQuotaRequest, this is currently supported only for allowlisted services.

pub const ADJUST_ONLY: QuotaMode

The operation allocates quota for the amount specified in the service configuration or specified using the quota metrics. If the requested amount is higher than the available quota, request does not fail and remaining quota would become negative (going over the limit). Not supported for Rate Quota.

pub fn value(&self) -> i32

Gets the enum value.

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

Gets the enum value as a string.

pub fn from_str_name(name: &str) -> Option<Self>

Creates an enum value from the value name.

Trait Implementations

impl Clone for QuotaMode

fn clone(&self) -> QuotaMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QuotaMode

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

Formats the value using the given formatter.

impl Default for QuotaMode

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QuotaMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<i32> for QuotaMode

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for QuotaMode

fn eq(&self, other: &QuotaMode) -> 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 QuotaMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
