gotypes

Some simple types based on builtin Golang types that implement interfaces for working with DB (Scan / Value) and JSON (Marshal / Unmarshal).

NullUint

Simplified sql.NullInt64 (but unsigned): not struct, based on builtin uint type.

ni := sql.NullInt64{Int64: 32, Valid: true}
// Corresponds to
nu := gotypes.NullUint(32)

ni := sql.NullInt64{Int64: 0, Valid: true}
// Corresponds to
nu := gotypes.NullUint(0)

ni := sql.NullInt64{Int64: 32, Valid: false}
// Corresponds to
nu := gotypes.NullUint(0)

NullString

Simplified sql.NullString: not struct, based on builtin string type.

ni := sql.NullString{String: "example", Valid: true}
// Corresponds to
nu := gotypes.NullString("example")

ni := sql.NullInt64{String: "", Valid: true}
// Corresponds to
nu := gotypes.NullString("")

ni := sql.NullInt64{String: "example", Valid: false}
// Corresponds to
nu := gotypes.NullString("")

Types

type NullString

type NullString string

NullString string. Empty value ” corresponds to db-value NULL. Строка. Пустое значение ” соответствует значению NULL в БД.

func (*NullString) Scan

func (ns *NullString) Scan(src interface{}) error

func (NullString) Value

func (ns NullString) Value() (driver.Value, error)

type NullUint

type NullUint uint

NullUint unsigned integer. Value 0 corresponds to db-value NULL. Беззнаковое целое. Значение 0 соответствует значению NULL в БД.

func (*NullUint) Scan

func (nu *NullUint) Scan(src interface{}) error

func (NullUint) Value

func (nu NullUint) Value() (driver.Value, error)
