Member Function Documentation

GenerateV7()

Uuid iceberg::Uuid::GenerateV7 ( uint64_t  unix_ts_ms )

static

Generate UUID version 7 per RFC 9562, with the given timestamp.

UUID version 7 consists of a Unix timestamp in milliseconds (48 bits) and 74 random bits, excluding the required version and variant bits.

Parameters

unix_ts_ms

number of milliseconds since start of the UNIX epoch

Note

unix_ts_ms cannot be negative per RFC.

operator[]()

uint8_t iceberg::Uuid::operator[]

(

size_t

index

)

const

Access individual bytes of the UUID.

Parameters

index

The index of the byte to access (0-15).

Returns

The byte at the specified index.

Exceptions

IcebergError

if index is out of bounds.

ToString()

std::string iceberg::Uuid::ToString ( ) const

overridevirtual

Convert the UUID to a string in standard format.

Implements iceberg::util::Formattable.
