Enum QuicBackend 

#[non_exhaustive]
pub enum QuicBackend {
    Quinn,
}

The QUIC backend to use for connections.

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.

Implementations

impl QuicBackend

pub fn compiled() -> &'static [Self]

Every backend this build was compiled with, spelled the way FromStr accepts.

The variants are feature-gated, so this is the only honest answer to “what can I pass here”. A caller building a menu should read it rather than listing the three names, which would offer options that cannot parse.

pub fn as_str(&self) -> &'static str

The name FromStr accepts for this backend.

Trait Implementations

impl Clone for QuicBackend

fn clone(&self) -> QuicBackend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuicBackend

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QuicBackend

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for QuicBackend

Parses the same spellings the CLI and TOML accept (quinn, quiche, noq), case-insensitively. A backend this build was compiled without is an error, since its variant doesn’t exist.

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Serialize for QuicBackend

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ValueEnum for QuicBackend

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
