Enum HsCircStemKind

Source 
#[non_exhaustive]
pub(crate) enum HsCircStemKind {
    Naive,
    Guarded,
}
Available on crate feature hs-common only.
Expand description

A kind of hidden service circuit stem.

See hspath docs for more information.

The structure of a circuit stem depends on whether vanguards are enabled:

  • with vanguards disabled:

       NAIVE   = G -> M -> M
   GUARDED = G -> M -> M

  • with lite vanguards enabled:

       NAIVE   = G -> L2 -> M
   GUARDED = G -> L2 -> M

  • with full vanguards enabled:

       NAIVE    = G -> L2 -> L3
   GUARDED = G -> L2 -> L3 -> M

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Naive

A naive circuit stem.

Used for building circuits to a final hop that an adversary cannot easily control, for example if the final hop is is randomly chosen by us.

§

Guarded

An guarded circuit stem.

Used for building circuits to a final hop that an adversary can easily control, for example if the final hop is not chosen by us.
