Variables

var Extractor = common.NewExtractor("config", (*Fact)(nil), Extract)

Extractor extracts config values relating to another decl, e.g. database configurations associated with a database decl.

Configs follow a pattern where they implement an interface, like `ftl.DatabaseConfig`. We extract values by looking at known receiver methods. For example:

type FooConfig struct{}

func (f FooConfig) Name() string {
    return "foo"
}

From this, we'd extract the "foo" value as the database name for `FooConfig`.

Functions

Types

type Fact

type Tag

type Tag struct{} // Tag uniquely identifies the fact type for this extractor.
