Struct ExtensionRejection 

pub struct ExtensionRejection { /* private fields */ }

Rejection returned when an extension is not found.

This rejection is returned by the Extension extractor when the requested type is not present in the router’s extensions.

Example

use tower_mcp::extract::ExtensionRejection;

let rejection = ExtensionRejection::not_found::<String>();
assert!(rejection.type_name().contains("String"));

Implementations

impl ExtensionRejection

pub fn not_found<T>() -> Self

Create a rejection for a missing extension type.

pub fn type_name(&self) -> &'static str

Get the type name of the missing extension.

Trait Implementations

impl Clone for ExtensionRejection

fn clone(&self) -> ExtensionRejection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionRejection

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

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ExtensionRejection> for Error

fn from(rejection: ExtensionRejection) -> Self
