Enum MetaValidationError 

#[non_exhaustive]
pub enum MetaValidationError {
    ExpectedObject,
    MissingExtensionPrefix(String),
    InvalidPrefix(String),
    InvalidName(String),
    InvalidExtensionSettings(String),
}

A protocol metadata key or extension declaration violated the MCP naming rules.

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.

ExpectedObject

A _meta value was not a JSON object.

MissingExtensionPrefix(String)

An extension identifier omitted its mandatory vendor prefix.

InvalidPrefix(String)

The prefix before / is malformed.

InvalidName(String)

The name after / (or the whole unprefixed key) is malformed.

InvalidExtensionSettings(String)

An extension’s settings value was not a JSON object.

Trait Implementations

impl Clone for MetaValidationError

fn clone(&self) -> MetaValidationError

impl Eq for MetaValidationError

impl Error for MetaValidationError

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
