Struct InvalidScope 

#[non_exhaustive]
pub struct InvalidScope { /* private fields */ }

Available on crate feature tower only.

A scope given to a route-level requirement (RequireScopes::try_new, the mcp feature’s McpToolScopes::try_default/try_tool) that is not an RFC 6749 §3.3 scope-token: empty, or holding a space, ", \, a control or non-ASCII character. No token can carry such a scope, so the requirement could never be met.

Scopes are configuration, not secrets: Display and scope name the offending value.

#[non_exhaustive]: read it through its accessor.

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
