func ImplementsScanner

func ImplementsScanner(named *types.Named) bool

ImplementsScanner reports whether or not the given named type implements the "database/sql.Scanner" interface. If the named type's underlying type is an interface type, ImplementsScanner will report whether or not that interface type declares, or embeds, the "Scan(interface{}) error" method.

func ImplementsValuer

func ImplementsValuer(named *types.Named) bool

ImplementsValuer reports whether or not the given named type implements the "database/sql/driver.Valuer" interface. If the named type's underlying type is an interface type, ImplementsValuer will report whether or not that interface type declares, or embeds, the "Value() (driver.Value, error)" method.

func ImplementsXMLMarshaler

func ImplementsXMLMarshaler(named *types.Named) bool

ImplementsXMLMarshaler reports whether or not the given named type implements the "encoding/xml.Marshaler" interface. If the named type's underlying type is an interface type, ImplementsXMLMarshaler will report whether or not that interface type declares, or embeds, the "MarshalXML(*xml.Encoder, xml.StartElement) (error)" method.

func ImplementsXMLUnmarshaler

func ImplementsXMLUnmarshaler(named *types.Named) bool

ImplementsXMLUnmarshaler reports whether or not the given named type implements the "encoding/xml.Unmarshaler" interface. If the named type's underlying type is an interface type, ImplementsXMLUnmarshaler will report whether or not that interface type declares, or embeds, the "UnmarshalXML(*xml.Decoder, xml.StartElement) (error)" method.

func IsContext

func IsContext(typ types.Type) bool

IsContext reports whether or not the given type is the standard "context.Context" type.

func IsDirective

func IsDirective(ident string, typ types.Type) bool

IsDirective reports whether or not the given type is a "github.com/frk/gosql" directive type.

func IsEmptyInterface

func IsEmptyInterface(typ types.Type) bool

IsEmptyInterface reports whether or not the given type is the "interface{}" type.

func IsEmptyInterfaceSlice

func IsEmptyInterfaceSlice(typ types.Type) bool

IsEmptyInterfaceSlice reports whether or not the given type is the "[]interface{}" type.

func IsError

func IsError(typ types.Type) bool

IsError reports whether or not the given type is the "error" type.

func IsJSONMarshaler

func IsJSONMarshaler(mm Methoder) bool

IsJSONMarshaler reports whether or not the given Methoder type declares, or embeds, the "MarshalJSON() ([]byte, error)" method.

func IsJSONUnmarshaler

func IsJSONUnmarshaler(mm Methoder) bool

IsJSONUnmarshaler reports whether or not the given Methoder type declares, or embeds, the "UnmarshalJSON([]byte) (error)" method.

func IsNiladicFunc

func IsNiladicFunc(typ types.Type) bool

IsNiladicFunc reports whether or not the given type is the "func()" type.

func IsScanner

func IsScanner(mm Methoder) bool

IsScanner reports whether or not the given Methoder type declares, or embeds, the "Scan(interface{}) error" method.

func IsSqlDriverValue

func IsSqlDriverValue(typ types.Type) bool

IsSqlDriverValue reports whether or not the given type is the "database/sql/driver.Value" type.

func IsSqlResult

func IsSqlResult(typ types.Type) bool

IsSqlResult reports whether or not the given type is the standard "sql.Result" type.

func IsSqlRowPtr

func IsSqlRowPtr(typ types.Type) bool

IsSqlRowPtr reports whether or not the given type is the standard "*sql.Row" type.

Types

type Methoder

type Methoder interface {
	NumMethods() int
	Method(i int) *types.Func
}

Methoder represents a type with methods. It is implicitly implemented by *types.Interface and *types.Named.

type NamedStruct

type NamedStruct struct {
	Named  *types.Named
	Struct *types.Struct
}

func GetStruct

func GetStruct(v *types.Var) (*NamedStruct, error)

GetStruct is a helper function that returns a *NamedStruct value that represents the struct type of the the given *types.Var. If the struct type is unnamed then the Named field of the *NamedStruct value will remain uninitialized. If the var's type is not a struct then GetStruct will return an error.
