Enum rustls::client::client_conn::ServerName

source ·
#[non_exhaustive]
pub enum ServerName { DnsName(DnsName), IpAddress(IpAddr), }
Expand description

Encodes ways a client can know the expected name of the server.

This currently covers knowing the DNS name of the server, but will be extended in the future to supporting privacy-preserving names for the server (“ECH”). For this reason this enum is non_exhaustive.

§Making one

If you have a DNS name as a &str, this type implements TryFrom<&str>, so you can do:

ServerName::try_from("example.com").expect("invalid DNS name");

// or, alternatively...

let x = "example.com".try_into().expect("invalid DNS name");

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.
§

DnsName(DnsName)

The server is identified by a DNS name. The name is sent in the TLS Server Name Indication (SNI) extension.

§

IpAddress(IpAddr)

The server is identified by an IP address. SNI is not done.

Implementations§

source§

impl ServerName

source

pub(crate) fn for_sni(&self) -> Option<DnsNameRef<'_>>

Return the name that should go in the SNI extension. If None is returned, the SNI extension is not included in the handshake.

impl PartialEq for ServerName

source§

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

1.0.0 · source§

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

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