You can deconstruct the data structure on your own like this:
val tag = EntityTag("kappa", weak = true)
val ifNoneMatch = `If-None-Match`(tag)
ifNoneMatch.m match {
case EntityTagRange.Default(tags) if tags.nonEmpty ⇒ tags.head.tag
case EntityTagRange.Default(tags) ⇒ ""
case EntityTagRange.`*` ⇒ ""
}
ifNoneMatch match {
case `If-None-Match`(EntityTagRange.Default(tags)) if tags.nonEmpty
⇒ tags.head.tag
case `If-None-Match`(EntityTagRange.Default(tags)) ⇒ ""
case `If-None-Match`(EntityTagRange.`*`) ⇒ ""
}
Happy hakking

On server side using scala, akka-http (10.x) I am using
*optionalHeaderValueByType[`If-None-Match`]()
{ reqETag => ... }* to extract `If-None-Match` header where reqETag is of
type *Option[If-None-Match].*
On client side, the If-None-Match is created using
val entityTag = EntityTag(SomeSecurishString, weak = true)
val ifNone = `If-None-Match`(entityTag)
On the server side I am looking to extract SomeSecureString, ie. the tag
value minus the prepended W/. I realize this can be done by
parsing/splitting value string but this feels real cumbersome and was
expecting an unapply function to come to the rescue.
*`If-None-Match`.unapply* returns EntityTagRange which doesn't help me much.
Any suggestions on how to extract the EntityTag's tag string from
`If-None-Match`
Much appreciated
