Types ¶
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client is used to fetch, cache, and parse schemas.
func NewHTTPClient ¶

type Converter ¶
type Converter struct {
// contains filtered or unexported fields
}
Converter converts OpenTelemetry objects based on OpenTelemetry schema translations.
func NewConverter ¶
NewConverter returns a new Converter that uses the Client c to handle all schema fetching. If c is nil, the default client will be used.
func (Converter) MergeResources ¶
func (c Converter) MergeResources(ctx context.Context, schemaURL string, resources ...*resource.Resource) (*resource.Resource, error)
MergeResources creates a new resource by combining resources at the target schemaURL version.
If there are common keys between resources the latter resource will overwrite the former.
Any of the resources not already at schemaURL version will be appropriately upgraded or downgraded to match the version. An error is returned if this is not possible.
func (Converter) Resource ¶
func (c Converter) Resource(ctx context.Context, schemaURL string, orig *resource.Resource) (*resource.Resource, error)
Resource returns a copy of orig with the schema URL set to url and all attributes transformed based on the associated schema. If the schema transformation fails, or url is empty, an error is returned.
