Struct Implementation 

pub struct Implementation {
    pub description: Option<String>,
    pub icons: Option<Vec<Icon>>,
    pub name: String,
    pub title: Option<String>,
    pub version: String,
    pub website_url: Option<String>,
}

Describes the MCP implementation.

Fields

description: Option<String>

An optional human-readable description of what this implementation does.

This can be used by clients or servers to provide context about their purpose and capabilities. For example, a server might describe the types of resources or tools it provides, while a client might describe its intended use case.

icons: Option<Vec<Icon>>

Optional set of sized icons that the client can display in a user interface.

Clients that support rendering icons MUST support at least the following MIME types:

• image/png - PNG images (safe, universal compatibility)
• image/jpeg (and image/jpg) - JPEG images (safe, universal compatibility)

Clients that support rendering icons SHOULD also support:

• image/svg+xml - SVG images (scalable but requires security precautions)
• image/webp - WebP images (modern, efficient format)

name: String

Intended for programmatic or logical use, but used as a display name in past specs or fallback (if title isn’t present).

title: Option<String>

Intended for UI and end-user contexts — optimized to be human-readable and easily understood, even by those unfamiliar with domain-specific terminology.

If not provided, the name should be used for display (except for Tool, where annotations.title should be given precedence over using name, if present).

version: String

The version of this implementation.

website_url: Option<String>

An optional URL of the website for this implementation.

Implementations

impl Implementation

pub fn new(name: String, version: String) -> Implementation

Creates a value from its required fields; optional fields are None.

Trait Implementations

impl Clone for Implementation

fn clone(&self) -> Implementation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Implementation

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

Formats the value using the given formatter.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<Implementation, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Implementation

fn eq(&self, other: &Implementation) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Implementation

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.
