Enum ProtocolVersion

pub enum ProtocolVersion {
    V2024_11_05,
    V2025_03_26,
    Custom(String),
}

MCP protocol version identifier.

The MCP protocol uses semantic versioning with date-based versions. This enum provides type-safe handling of supported protocol versions.

Variants

V2024_11_05

MCP Protocol version 2024-11-05 (legacy)

V2025_03_26

MCP Protocol version 2025-03-26 (current stable)

Custom(String)

Future protocol versions can be added here Custom version string for forward compatibility

Implementations

impl ProtocolVersion

pub fn as_str(&self) -> &str

Get the string representation of the protocol version.

pub fn is_supported(&self) -> bool

Check if this version is supported by the current implementation.

pub fn supported_versions() -> Vec<Self>

Get all supported protocol versions.

Trait Implementations

impl Clone for ProtocolVersion

fn clone(&self) -> ProtocolVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolVersion

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

Formats the value using the given formatter.

impl Default for ProtocolVersion

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProtocolVersion

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProtocolVersion

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

Formats the value using the given formatter.

impl Hash for ProtocolVersion

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ProtocolVersion

fn eq(&self, other: &ProtocolVersion) -> 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 Serialize for ProtocolVersion

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
