Enum RpcMetadataError 

#[non_exhaustive]
pub enum RpcMetadataError {
    InvalidAsciiKey {
        key: String,
    },
    InvalidAsciiValue {
        key: String,
        value: String,
    },
    InvalidBinaryKey {
        key: String,
    },
}

An invalid key or value supplied to RpcMetadata.

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.

InvalidAsciiKey

The key is not valid ASCII gRPC metadata.

Fields

key: String

The invalid key.

InvalidAsciiValue

The value is not valid ASCII gRPC metadata.

Fields

key: String

The associated key.

value: String

The invalid value.

InvalidBinaryKey

The key is not valid binary gRPC metadata.

Fields

key: String

The invalid key.

Trait Implementations

impl Eq for RpcMetadataError

impl Error for RpcMetadataError

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.
