Overview ¶
Package dataconv provides helper functions to convert between Starlark and Go types. It works like package starlight, but only supports common Starlark and Go types, and won't wrap any custom types or functions.

Functions ¶
func IsEmptyString ¶
IsEmptyString checks is a starlark string is empty ("" for a go string) starlark.String.String performs repr-style quotation, which is necessary for the starlark.Value contract but a frequent source of errors in API clients. This helper method makes sure it'll work properly
func IsInterfaceNil ¶
func IsInterfaceNil(i interface{}) bool
IsInterfaceNil returns true if the given interface is nil.
func Marshal ¶
Marshal converts Go values into Starlark types, like ToValue() of package starlight does. It only supports common Go types, won't wrap any custom types like Starlight does.
func MarshalStarlarkJSON ¶
MarshalStarlarkJSON marshals a starlark.Value into a JSON string. It first converts the starlark.Value into a Golang value, then marshals it into JSON.
Types ¶
type Marshaler ¶
type Marshaler interface {
// MarshalStarlark marshal a custom type to Starlark object.
MarshalStarlark() (starlark.Value, error)
}
Marshaler is the interface use to marshal Starlark from custom types, i.e. Go to Starlark.
type Unmarshaler ¶
type Unmarshaler interface {
// UnmarshalStarlark unmarshal a Starlark object to custom type.
UnmarshalStarlark(starlark.Value) error
}
Unmarshaler is the interface use to unmarshal Starlark values to custom types, i.e. Starlark to Go.
