Error returned by aggregate_candles for invalid arguments or input.

Every variant is an observable failure: the aggregation never silently repairs, reorders or drops input.

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.

NonPositiveInterval

base_interval or target is zero or negative.

Fields

base: Duration

The base_interval argument as supplied.

target: Duration

The target argument as supplied.

SubMillisecondInterval

base_interval or target has a sub-millisecond component. Bucketing operates at millisecond granularity (venue candle timestamps are millisecond-resolution), so a sub-millisecond interval would silently mis-bucket — it is rejected instead.

Fields

base: Duration

The base_interval argument as supplied.

target: Duration

The target argument as supplied.

TargetSmallerThanBase

target is shorter than base_interval — aggregation only coarsens.

Fields

base: Duration

The base_interval argument as supplied.

target: Duration

The target argument as supplied.

TargetNotMultipleOfBase

target is not an integer multiple of base_interval, so base candles cannot tile target buckets exactly.

Fields

base: Duration

The base_interval argument as supplied.

target: Duration

The target argument as supplied.

NonMonotonicInput

The input candle at index is not strictly later (by close_time) than its predecessor. Strictness also rejects duplicate timestamps: no two distinct fixed-interval candles can legitimately share a close_time, so a duplicate is a data bug (e.g. an overlapping-page double fetch) whose volume must not be double-counted.

Fields

index: usize

Index into the input slice of the offending candle.

TimestampOutOfRange

A boundary computed for the candle at index falls outside the representable DateTime<Utc> range. Three computations can fail this way: the sub-bar open underflowed (input near the minimum instant); the bucket’s epoch-grid-floored open underflowed (flooring a representable open onto a coarse target grid can still land below the minimum instant); or the bucket close_time overflowed (input near the maximum instant).

Fields

index: usize

Index into the input slice attributing the failure: the offending candle itself for a sub-bar open underflow, or the affected bucket’s first sub-bar for a bucket-level boundary failure (whose own sub-bar boundary need not be invalid).
