Enum ALPN 

pub enum ALPN {
    H1,
    H2,
    H2H1,
    Custom(CustomALPN),
}

The protocol for Application-Layer Protocol Negotiation

Variants

H1

Prefer HTTP/1.1 only

H2

Prefer HTTP/2 only

H2H1

Prefer HTTP/2 over HTTP/1.1

Custom(CustomALPN)

Custom Protocol is stored in wire format (length-prefixed) Wire format is precomputed at creation to avoid dangling references

Implementations

impl ALPN

pub fn new(max: u8, min: u8) -> Self

pub fn get_max_http_version(&self) -> u8

Return the max http version this ALPN allows

pub fn get_min_http_version(&self) -> u8

Return the min http version this ALPN allows
