func Int32FromString 

func Int32FromString(v string) (int32, error)

Int32FromString converts a string to an int32

func JQReadConstant 

func JQReadConstant[T any](constant any) (T, error)

JQReadConstant gets the typed value from the given constant. Returns an error when the type assertion fails.

func JQReadFrom 

func JQReadFrom[T any](ctx context.Context, path string, obj any) (T, error)

JQReadFrom gets the typed value from the given accessor. Returns an error when the accessor doesn't find anything or when the type assertion fails. Useful for when you know the type you're expecting AND the accessor must return a value (IOW, the value is required by the caller)

func OpenFileArg 

func OpenFileArg(f string, dashOpen io.Reader) (desc io.Reader, closer func(), err error)

OpenFileArg opens a file argument and returns a descriptor, closer, and error If the file is "-", it will return whatever is passed in as dashOpen and a no-op closer

func RemoveCredentials 

func RemoveCredentials() error

RemoveCredentials removes the local credentials file

func RevokeOfflineToken 

func RevokeOfflineToken(token string, issuerUrl string, clientId string) error

RevokeOfflineToken revokes the given offline token using OAuth2.0's Token Revocation endpoint from RFC 7009.

func RevokeToken 

func RevokeToken(token string, issuerUrl string, clientId string, tokenHint string) error

RevokeToken revokes the given token using OAuth2.0's Token Revocation endpoint from RFC 7009. The tokenHint is the type of token being revoked, such as "access_token" or "refresh_token". In the case of an offline token, the tokenHint should be "refresh_token".

func SanitizingInterceptor 

func SanitizingInterceptor() grpc.UnaryServerInterceptor

SanitizingInterceptor sanitized error statuses which do not conform to NiceStatus, ensuring that we don't accidentally leak implementation details over gRPC.

func SaveCredentials 

func SaveCredentials(tokens OpenIdCredentials) (string, error)
