Struct ProtocolVersion 

pub struct ProtocolVersion(/* private fields */);

Represents the MCP protocol version used for communication.

This ensures compatibility between clients and servers by specifying which version of the Model Context Protocol is being used.

Implementations

impl ProtocolVersion

pub const V_2025_06_18: ProtocolVersion

pub const V_2025_03_26: ProtocolVersion

pub const V_2024_11_05: ProtocolVersion

pub const LATEST: ProtocolVersion = Self::V_2025_06_18

pub const KNOWN_VERSIONS: &'static [ProtocolVersion]

All protocol versions known to this SDK.

pub fn as_str(&self) -> &str

Returns the string representation of this protocol version.

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<(), Error>

Formats the value using the given formatter.

impl Default for ProtocolVersion

fn default() -> ProtocolVersion

Returns the “default value” for a type.

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

fn deserialize<D>( deserializer: D, ) -> Result<ProtocolVersion, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ProtocolVersion

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

Formats the value using the given formatter.

impl Hash for ProtocolVersion

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

where __H: Hasher,

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 PartialOrd for ProtocolVersion

fn partial_cmp(&self, other: &ProtocolVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for ProtocolVersion

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
