Rename the
header-error
variant tovalidation-error
, and use that variant as the error value for all setters ofoutbound-request
andoutbound-response
. This ensures that we have the opportunity to validate outbound request and response values before they're given to their respective handlers.Validation for uri components is done by using
http:uri::Builder
with only that value, ensuring that we don't raise an error. Validation for method and scheme is only done for theOther
cases, and is accomplished by using the fallible parsers for each type from thehttp
crate.
