Enum McpAuthError 

#[non_exhaustive]
pub enum McpAuthError {
    BridgeUnreachable(String),
    TokenExchangeFailed {
        status: u16,
        body: String,
    },
    InvalidResponse(String),
    InsufficientCapabilities {
        requested: Vec<String>,
        detail: String,
    },
}

Errors from MCP token exchange operations.

Usage:

match result {
    Err(McpAuthError::BridgeUnreachable(msg)) => { /* retry later */ }
    Err(McpAuthError::InsufficientCapabilities { .. }) => { /* request fewer caps */ }
    Err(e) => return Err(e.into()),
    Ok(token) => { /* use token */ }
}

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

BridgeUnreachable(String)

The OIDC bridge is unreachable.

TokenExchangeFailed

The bridge returned a non-success status.

Fields

status: u16

HTTP status code from the bridge.

body: String

Response body.

InvalidResponse(String)

The bridge response could not be parsed.

InsufficientCapabilities

The bridge rejected the requested capabilities.

Fields

requested: Vec<String>

The capabilities that were requested.

detail: String

Detail from the bridge error response.

Trait Implementations

impl AuthsErrorInfo for McpAuthError

fn error_code(&self) -> &'static str

Returns a unique error code string for this error variant.

fn suggestion(&self) -> Option<&'static str>

Returns an optional actionable suggestion for resolving the error.

impl Debug for McpAuthError

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

Formats the value using the given formatter.

impl Display for McpAuthError

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

Formats the value using the given formatter.

impl Error for McpAuthError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.
