Types ¶

type Field ¶

type Field struct {
	Column string

	// Whether this field is read-only, meaning it should not be used for inserts/updatesbe scanned into.
	ReadOnly bool
	// Full field index to this field from our root struct
	Index []int
	// Direct type of field, equal to Type unless pointer
	DirectType reflect.Type
	// Type of field, may be a pointer.
	Type reflect.Type
	// contains filtered or unexported fields
}

Field represents a Field in a struct. Adapted from json package reflection. Key difference is json recursively encodes/decodes, we're handling flat tabular data.

func (*Field) Fields ¶

func (f *Field) Fields() *Fields

Get the sub fields of this field when it's a struct itself.

func (*Field) IsEmbeddedStruct ¶

func (f *Field) IsEmbeddedStruct() bool

type Fields ¶

type Fields struct {
	ByColumnName map[string]*Field
	Type         reflect.Type
}

Fields represents the fields of a struct.

func FieldsFactory ¶

func FieldsFactory(t reflect.Type) (*Fields, error)

Internally, all types are stored in a cache to avoid repeated work.

func (*Fields) IsEmbeddedStruct ¶

func (f *Fields) IsEmbeddedStruct() bool

func (*Fields) Rows ¶

func (f *Fields) Rows(rows *sql.Rows) (*FieldsRows, error)

func (*Fields) Writable ¶

func (f *Fields) Writable() map[string]*Field

WriteFields returns the fields that can be written to (ie. are actual columns in table). This is based on struct tags and heuristics around anonymous embeds.

type FieldsRows ¶

type FieldsRows struct {
	*sql.Rows
	// contains filtered or unexported fields
}

FieldsRows handles scanning rows into given struct field.

func NewFieldsRows ¶

func NewFieldsRows(f *Fields, rows *sql.Rows) (*FieldsRows, error)

func (*FieldsRows) Scan ¶

func (sr *FieldsRows) Scan(_val ...reflect.Value) (reflect.Value, error)

Scan a row into reflected value. Will automatically setup a new value if needed
