Types

type Config 

type Config struct {
	RowType    reflect.Type
	Columns    []*data.Column
	Factory    xcodec.Factory
	LookupType func(string) (reflect.Type, error)
	Resources  fs.FS
}

type Decoder 

type Decoder struct {
	// contains filtered or unexported fields
}

Decoder is per-query state. SQLX owns both scan destinations and cache bytes.

func (*Decoder) Decode 

func (d *Decoder) Decode(ctx context.Context, row any) (any, error)

func (*Decoder) FieldIndexes 

func (d *Decoder) FieldIndexes() ([][]int, error)

FieldIndexes translates the actual native scan mapping through this codec's already-compiled target accessors. Virtual Raw/Shadow wrapper fields never escape as model-field evidence.

func (*Decoder) NewRow 

func (d *Decoder) NewRow() any

func (*Decoder) Observe 

func (d *Decoder) Observe(columns []sqlxio.Column) error

Observe delegates field identity to SQLX's matcher; no mapping is replaced.

type Plan 

type Plan struct {
	// contains filtered or unexported fields
}

Plan contains immutable source/destination contracts; Decode state is per read.

func Compile 

func Compile(config Config) (*Plan, error)

func (*Plan) ModelType 

func (p *Plan) ModelType() reflect.Type

func (*Plan) NewDecoder 

func (p *Plan) NewDecoder(newActual func() any, options ...xcodec.Option) *Decoder
