Enum ChainSeparator 

pub enum ChainSeparator {
    NotFoundOnly,
    AnyError,
}

Which fallback rule governs a GOPROXY chain hop’s failure (spec 034 S2).

go help goproxy and Go’s own modfetch/proxy.go give , and | genuinely different semantics — this crate’s ,-and-|-both-fall-through-on-not-found first cut collapsed that distinction; see GoRegistry::get_versions_chained (registry.rs) for where this is consulted.

Variants

NotFoundOnly

,: fall through to the next hop only on an explicit not-found response (404/410) — a transport failure (timeout, connection error, 5xx) is terminal for the whole chain.

AnyError

|: fall through to the next hop on any error, including a transport failure.

Trait Implementations

impl Clone for ChainSeparator

fn clone(&self) -> ChainSeparator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChainSeparator

impl Debug for ChainSeparator

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

Formats the value using the given formatter.

impl Eq for ChainSeparator

impl PartialEq for ChainSeparator

fn eq(&self, other: &ChainSeparator) -> 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.
