Enum InvalidSniPolicy 

#[non_exhaustive]
pub enum InvalidSniPolicy {
    RejectAll,
    IgnoreIpAddresses,
    IgnoreAll,
}

A policy describing how an invalid Server Name Indication (SNI) value from a client is handled by the server.

The only valid form of SNI according to relevant RFCs (RFC6066, RFC1035) is non-IP-address host name, however some misconfigured clients may send a bare IP address, or another invalid value. Some servers may wish to ignore these invalid values instead of producing an error.

By default, Rustls will ignore invalid values that are an IP address (the most common misconfiguration) and error for all other invalid values.

When an SNI value is ignored, Rustls treats the client as if it sent no SNI at all.

Variants (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.

RejectAll

Reject all ClientHello messages that contain an invalid SNI value.

IgnoreIpAddresses

Ignore an invalid SNI value in ClientHello messages if the value is an IP address.

“Ignoring SNI” means accepting the ClientHello message, but acting as if the client sent no SNI.

IgnoreAll

Ignore all invalid SNI in ClientHello messages.

“Ignoring SNI” means accepting the ClientHello message, but acting as if the client sent no SNI.

Trait Implementations

impl Clone for InvalidSniPolicy

fn clone(&self) -> InvalidSniPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidSniPolicy

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

Formats the value using the given formatter.

impl Default for InvalidSniPolicy

fn default() -> InvalidSniPolicy

Returns the “default value” for a type.

impl PartialEq for InvalidSniPolicy

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