Enum DowngradeCause 

pub enum DowngradeCause {
    ProxyConfigured,
}

Why a protocol downgrade occurred — T105 only has one cause today (operator-configured HTTP proxy), but the variant is open for future causes (e.g. tunnel wrappers that strip UDP).

Variants

ProxyConfigured

Operator configured an HTTP proxy URL — Chrome is TCP-only over SOCKS5 in practice and HTTP proxies tunnel TCP only, so even with prefer_h3 = true the negotiated protocol falls back to HTTP/2 (per Web Scraping Guide §Innovation).

Trait Implementations

impl Clone for DowngradeCause

fn clone(&self) -> DowngradeCause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DowngradeCause

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DowngradeCause

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DowngradeCause

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

Formats the value using the given formatter.

impl Eq for DowngradeCause

impl PartialEq for DowngradeCause

fn eq(&self, other: &DowngradeCause) -> 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 Serialize for DowngradeCause

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
