Struct UnusableFill 

pub struct UnusableFill {
    pub token: u64,
    pub reason: &'static str,
}

One fill a reader cannot use, and why. Per token rather than per set, because a key has one UnusableFills and a set-wide reason would attribute one part of an application’s give-up to another’s cause.

Fields

token: u64

Names a fill this reader cannot use. Opaque to the cache: whatever the writer and reader agree it means.

reason: &'static str

Why, as the crate::NoCacheReason::Custom label the cache disables with. Not a whole crate::NoCacheReason: the cause belongs to the application, and a caller could otherwise pass crate::NoCacheReason::NeverEnabled, which crate::HttpCache::disable rejects.
