ConvertingMismatch

sealed class ConvertingMismatch(val column: String, val row: Int?, val cause: Exception?)

Detailed message about any mismatch when saving to Arrow format with a user-defined schema that does not match the actual data. Can be sent to a callback, written to a log, or wrapped in an exception

Types

NarrowingMismatch

sealed class NarrowingMismatch(column: String) : ConvertingMismatch

NullableMismatch

sealed class NullableMismatch(column: String, row: Int?) : ConvertingMismatch

PrecisionReduced

data class PrecisionReduced(val column: String, val row: Int?, val unit: String) : ConvertingMismatch

A date-time value did not fit the target field's precision and its trailing digits were dropped — for example a nanosecond instant saved into a Timestamp(MICROSECOND, …) field.

SavedAsString

data class SavedAsString(val column: String, val type: Class<*>) : ConvertingMismatch

TypeConversionFail

sealed class TypeConversionFail(column: String, row: Int?, val cause: CellConversionException) : ConvertingMismatch

TypeConversionNotFound

sealed class TypeConversionNotFound(column: String, cause: TypeConverterNotFoundException) : ConvertingMismatch

ValueOutOfRange

data class ValueOutOfRange(val column: String, val row: Int?, val unit: String) : ConvertingMismatch

A date-time value did not fit the target field's range at all — for example an instant in the year 2500 saved into a Timestamp(NANOSECOND, …) field, which is an int64 nanosecond count and so only spans 1677–2262.
