Struct Implementation 

#[non_exhaustive]
pub struct Implementation {
    pub name: String,
    pub title: Option<String>,
    pub version: String,
    pub meta: Option<Meta>,
}

Metadata about the implementation of the client or agent. Describes the name and version of an MCP implementation, with an optional title for UI representation.

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

Intended for programmatic or logical use, but can be used as a display name fallback if title isn’t present.

title: Option<String>

Intended for UI and end-user contexts — optimized to be human-readable and easily understood.

If not provided, the name should be used for display.

version: String

Version of the implementation. Can be displayed to the user or used for debugging or metrics purposes. (e.g. “1.0.0”).

meta: Option<Meta>

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility

Implementations

impl Implementation

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

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

Intended for UI and end-user contexts — optimized to be human-readable and easily understood.

If not provided, the name should be used for display.

pub fn meta(self, meta: impl IntoOption<Meta>) -> Self

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. Implementations MUST NOT make assumptions about values at these keys.

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

Formats the value using the given formatter.

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 JsonSchema for Implementation

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Implementation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Implementation
