Struct Endpoint 

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

The path a client POSTs, GETs and DELETEs, without a scheme or host.

The specification calls this the “MCP endpoint” and gives https:// example.com/mcp as its example. Only the path is kept, because the adapter is handed a Router and mounting is the caller’s decision — a server that also serves a web UI mounts the same router under a different base and the endpoint is the part the MCP specification actually constrains.

Implementations

impl Endpoint

pub const DEFAULT: &'static str = "/mcp"

The default the specification’s own example uses.

pub fn as_str(&self) -> &str

The path, for axum::Router::route.

Trait Implementations

impl Clone for Endpoint

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Endpoint

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

Formats the value using the given formatter.

impl Display for Endpoint

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

Formats the value using the given formatter.

impl Eq for Endpoint

impl FromStr for Endpoint

fn from_str(value: &str) -> Result<Self, Self::Err>

Errors

EndpointError::Empty for a blank path, EndpointError::NoLeadingSlash because axum matches paths that begin with one and would otherwise register a route that can never fire, EndpointError::QueryOrFragment because a ? or # never reaches a server — the client strips both before writing the request line — so an endpoint containing one is a route that can never fire and a configuration mistake, and EndpointError::NotVisibleAscii because a path is spliced into a request line.

Surrounding whitespace is trimmed rather than refused, on the same grounds as McpSessionId::validate: a path copied out of a config file or a URL bar routinely arrives with a trailing newline, and treating that as a hard error is a footgun with no security value.

type Err = EndpointError

The associated error which can be returned from parsing.

impl Hash for Endpoint

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 Endpoint

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

Equality operator ==.

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

Inequality operator !=.
