Enum Route 

pub enum Route {
    Deny,
    ClusterId(ClusterId),
    Frontend(Rc<Frontend>),
}

What to do with a request that matches a frontend.

Three variants coexist today; the legacy two will retire once HttpFrontend itself carries the rich routing fields:

• Route::ClusterId is the legacy “forward to this cluster” variant used by call sites that build routes directly from HttpFrontend::cluster_id.
• Route::Deny is the legacy “send 401” variant used when a frontend has no cluster_id.
• Route::Frontend carries a richer Frontend decision (redirect policy, rewrite templates, header edits, auth gating). Once HttpFrontend carries the matching proto fields, add_http_front will build Route::Frontend directly and the two legacy variants above can retire.

Eq/PartialEq compare Frontend variants by Rc pointer identity to stay consistent with Hash/Ord on Rc; this is sufficient for the router’s de-duplication (add_pre_rule, add_post_rule, add_tree_rule) which only checks against routes created from the same configuration call.

Variants

Deny

send a 401 default answer

ClusterId(ClusterId)

the cluster to which the frontend belongs

Frontend(Rc<Frontend>)

rich routing decision carrying redirect, rewrite, header, and auth configuration; supersedes the two legacy variants once the in-memory frontend wiring is migrated to build Route::Frontend directly.

Trait Implementations

impl Clone for Route

fn clone(&self) -> Route

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Route

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Route

impl Hash for Route

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Route

fn cmp(&self, other: &Route) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Route

fn eq(&self, other: &Route) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Route

fn partial_cmp(&self, other: &Route) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
