Struct Implementation 

#[non_exhaustive]
pub struct Implementation {
    pub name: String,
    pub title: Option<String>,
    pub version: String,
    pub website_url: Option<String>,
    pub description: Option<String>,
    pub icons: Option<Vec<IconInfo>>,
}

Implementation information.

Backward Compatibility

This struct is #[non_exhaustive]. Use the constructor and fluent methods to remain forward-compatible:

use pmcp::types::protocol::Implementation;

let info = Implementation::new("my-server", "1.0.0")
    .with_title("My Server")
    .with_description("A great server");

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Implementation name (e.g., “mcp-sdk-rust”)

title: Option<String>

Optional human-readable title (MCP 2025-11-25)

version: String

Implementation version

website_url: Option<String>

Optional website URL (MCP 2025-11-25)

description: Option<String>

Optional description (MCP 2025-11-25)

icons: Option<Vec<IconInfo>>

Optional icons (MCP 2025-11-25)

Implementations

impl Implementation

pub fn new(name: impl Into<String>, version: impl Into<String>) -> Self

Create an Implementation with just name and version.

The optional 2025-11-25 fields (title, website_url, description, icons) default to None.

pub fn with_title(self, title: impl Into<String>) -> Self

Set a human-readable title (MCP 2025-11-25).

pub fn with_website_url(self, url: impl Into<String>) -> Self

Set the website URL (MCP 2025-11-25).

pub fn with_description(self, description: impl Into<String>) -> Self

Set a human-readable description (MCP 2025-11-25).

pub fn with_icons(self, icons: Vec<IconInfo>) -> Self

Set icons for the implementation (MCP 2025-11-25).

Trait Implementations

impl Clone for Implementation

fn clone(&self) -> Implementation

Returns a duplicate of the value.

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

impl Debug for Implementation

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

Formats the value using the given formatter.

impl Default for Implementation

fn default() -> Implementation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Implementation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Implementation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
