Enum TimeSeriesGranularity 

pub enum TimeSeriesGranularity {
    Seconds,
    Minutes,
    Hours,
    Custom {
        bucket_max_span_seconds: u32,
        bucket_rounding_seconds: u32,
    },
}

Time series bucketing granularity.

Controls the bucket span for time series collections:

Granularity	Bucket Span
Seconds	1 hour
Minutes	24 hours
Hours	30 days
Custom	User-defined (MongoDB ≥ 6.3)

Granularity can only increase (seconds → minutes → hours) on an existing collection. Attempting to decrease returns GranularityDecreaseDenied.

Variants

Seconds

Bucket span = 1 hour (default).

Minutes

Bucket span = 24 hours.

Hours

Bucket span = 30 days.

Custom

Custom bucketing (MongoDB ≥ 6.3).

Invariant: bucket_max_span_seconds must equal bucket_rounding_seconds. This is enforced at construction via TimeSeriesGranularity::custom.

Fields

bucket_max_span_seconds: u32

Maximum span of a single bucket in seconds.

bucket_rounding_seconds: u32

Rounding boundary in seconds (must equal bucket_max_span_seconds).

Implementations

impl TimeSeriesGranularity

pub fn custom( bucket_max_span_seconds: u32, bucket_rounding_seconds: u32, ) -> Result<Self, ConnectorError>

Creates a Custom granularity, enforcing the invariant that bucket_max_span_seconds == bucket_rounding_seconds.

Errors

Returns ConnectorError::ConfigurationError if the values differ.

pub fn is_finer_or_equal(self, other: Self) -> bool

Returns true if self is a finer (or equal) granularity than other.

Used to validate that granularity changes only increase.

pub fn validate_change( current: Self, requested: Self, ) -> Result<(), ConnectorError>

Validates that changing from current to requested is allowed.

Errors

Returns ConnectorError::ConfigurationError if the change would decrease granularity.

Trait Implementations

impl Clone for TimeSeriesGranularity

fn clone(&self) -> TimeSeriesGranularity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimeSeriesGranularity

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

Formats the value using the given formatter.

impl Default for TimeSeriesGranularity

fn default() -> TimeSeriesGranularity

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TimeSeriesGranularity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TimeSeriesGranularity

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

Formats the value using the given formatter.

impl Hash for TimeSeriesGranularity

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 TimeSeriesGranularity

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
