Enum VersionPolicy 

pub enum VersionPolicy {
    Auto,
    Exact(FciVersion),
}

How crate::Robot decides which FCI protocol version to speak.

The two supported versions are not distinguishable before the Connect handshake, so the default probes: FCI v10 first, then FCI v5 if the server rejects it and reports version 5.

Variants

Auto

Connect as FCI v10 (FR3). If the server answers kIncompatibleLibraryVersion reporting version 5, close both sockets and reconnect once as FCI v5 (FER). Any other server version is reported as crate::error::FrankaError::IncompatibleVersion.

Exact(FciVersion)

Connect as exactly this version and never retry; a mismatch is crate::error::FrankaError::IncompatibleVersion.

Trait Implementations

impl Clone for VersionPolicy

fn clone(&self) -> VersionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VersionPolicy

impl Debug for VersionPolicy

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

Formats the value using the given formatter.

impl Default for VersionPolicy

fn default() -> VersionPolicy

Returns the “default value” for a type.

impl Eq for VersionPolicy

impl PartialEq for VersionPolicy

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