VersionPolicyError

rama::quic::proto::version

Enum VersionPolicyError 

#[non_exhaustive]
pub enum VersionPolicyError {
    MissingOriginal,
    Empty,
    Unknown(Version),
    Reserved(Version),
    Incompatible(Version, Version),
    SwitchUnsupported,
}
Available on crate feature quic only.
Expand description

Why a version policy is not usable.

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.
§

MissingOriginal

A list must contain the version the first flight uses.

§

Empty

A list must not be empty.

§

Unknown(Version)

This crate does not implement the version.

§

Reserved(Version)

Reserved 0x?a?a?a?a versions are greased into lists, never listed as usable.

§

Incompatible(Version, Version)

Versions that are not compatible with each other cannot be offered for compatible negotiation (RFC 9368 §2.2).

§

SwitchUnsupported

The TLS provider cannot change version during the handshake, so it can only offer the version it starts with.
