Functions

func DivideCeil 

func DivideCeil(count int64, pageSize int64) int64

DivideCeil divides two integers and rounds up, rather than down (which is what happens when you do int64/int64).

func Fields 

func Fields(s string) ([]int64, error)

Fields splits a strings with strings.Fields() and parses each entry as an integer.

func Join 

func Join[T integer](ints []T, sep string) string

Join a slice of ints to a comma separated string with the given separator.

func Range 

func Range(start, end int) []int

Range creates an []int counting at "start" up to (and including) "end".

func RoundToPowerOf2 

func RoundToPowerOf2(n uint64) uint64

RoundToPowerOf2 rounds up to the nearest power of 2.

func Split 

func Split(s string, sep string) ([]int64, error)

Split a string to a slice of []int64.

func ToIntSlice 

func ToIntSlice(v any) ([]int64, bool)

ToIntSlice converts any []int type to an []int64.

func ToUintSlice 

func ToUintSlice(v any) ([]uint64, bool)

ToUintSlice converts any []int type to an []uint64.

type Uint128 

type Uint128 [2]uint64

Uint128 is an unsigned 128-bit integer.

Mostly intended to store UUIDs; storing it as a []byte takes up 40 bytes, whereas storing it in two uint64s takes up 16 bytes.

It's stored in so-called "big endian" format; that is, the most significant bit is on the right.

func NewUint128 

func NewUint128(b []byte) (Uint128, error)

NewUint128 creates a new uint128 from a [16]byte.

func ParseUint128 

func ParseUint128(s string, base int) (Uint128, error)

func (Uint128) Bytes 

func (i Uint128) Bytes() []byte

func (Uint128) Format 

func (i Uint128) Format(base int) string

Format according to the given base.

TODO: this is not really printin a number, but just printing the 2 numbers side-by-side, rather than actually adding up the bits.

func (Uint128) IsZero 

func (i Uint128) IsZero() bool

func (Uint128) MarshalText 

func (i Uint128) MarshalText() ([]byte, error)

MarshalText converts the data to a human readable representation.

func (*Uint128) New 

func (i *Uint128) New(b []byte) error

New sets this uint128 from a [16]byte.

func (*Uint128) Parse 

func (i *Uint128) Parse(str string, base int) error

func (*Uint128) Scan 

func (i *Uint128) Scan(v any) error

Scan converts the data from the DB.

func (Uint128) String 

func (i Uint128) String() string

func (Uint128) UUID 

func (i Uint128) UUID() string

UUID formats as a UUID.

func (*Uint128) UnmarshalText 

func (i *Uint128) UnmarshalText(v []byte) error

UnmarshalText parses text in to the Go data structure.

func (Uint128) Value 

func (i Uint128) Value() (driver.Value, error)

Value determines what to store in the DB.
