Git protocol capabilities

Implementation Status Overview

Implemented capabilities:

• Data transmission: SideBand, SideBand64k - Multiplexed data streams via side-band formatter
• Status reporting: ReportStatus, ReportStatusv2 - Push status feedback via protocol handlers
• Pack optimization: OfsDelta, ThinPack, NoThin - Delta compression and efficient transmission
• Protocol control: MultiAckDetailed, NoDone - ACK mechanism optimization for upload-pack
• Push control: Atomic, DeleteRefs, Quiet - Atomic operations and reference management
• Tag handling: IncludeTag - Automatic tag inclusion for upload-pack
• Client identification: Agent - Client/server identification in capability negotiation

Not yet implemented capabilities:

• Basic protocol: MultiAck - Basic multi-ack support (only detailed version implemented)
• Shallow cloning: Shallow, DeepenSince, DeepenNot, DeepenRelative - Depth control for shallow clones
• Progress control: NoProgress - Progress output suppression
• Special fetch: AllowTipSha1InWant, AllowReachableSha1InWant - SHA1 validation in want processing
• Security: PushCert - Push certificate verification mechanism
• Extensions: PushOptions, Filter, Symref - Extended parameter handling
• Session management: SessionId, ObjectFormat - Session and format negotiation

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl Display for Capability

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

Formats the value using the given formatter.

impl FromStr for Capability

type Err = ()

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 PartialEq for Capability

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

impl StructuralPartialEq for Capability
