Enum ForbiddenTrailers 

pub enum ForbiddenTrailers {
    DenyAll,
    AllowAll,
    AllowSome(Box<[HeaderName]>),
    DenySome(Box<[HeaderName]>),
}

Available on crate features http and std only.

Which fields a message’s trailer section sends although their definitions do not allow them in trailers.

Insert it into a message’s extensions; without one, Self::DenyAll applies. A response inherits it from its request, so a relay inserts it once into the request it forwards, and a message can override what it inherits. Fields that is_never_a_trailer names are never sent, whatever it allows.

Variants

DenyAll

None of them: only fields whose definitions allow trailers are sent.

AllowAll

All of them, as a relay forwarding what it received does.

AllowSome(Box<[HeaderName]>)

These only.

DenySome(Box<[HeaderName]>)

All but these.
