Enum AnyError 

#[non_exhaustive]
pub enum AnyError {
    Serialization(Box<dyn Error + Send + Sync>),
    Deserialization(Box<dyn Error + Send + Sync>),
    TypeMismatch {
        has: String,
        want: String,
    },
}

Indicates a problem trying to use an Any.

Example

use serde_json::json;
let any = serde_json::from_value::<Any>(json!({
    "@type": "type.googleapis.com/google.protobuf.Duration",
    "value": "123.5" // missing `s` suffix
}))?;
let extracted = any.to_msg::<Duration>();
assert!(matches!(extracted, Err(AnyError::Deserialization(_))));

Example

let duration = Duration::clamp(60, 0);
let any = Any::from_msg(&duration)?;
let extracted = any.to_msg::<Timestamp>();
assert!(matches!(extracted, Err(AnyError::TypeMismatch{..})));

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.

Serialization(Box<dyn Error + Send + Sync>)

Problem serializing an object into an Any.

Deserialization(Box<dyn Error + Send + Sync>)

Problem deserializing an object from an Any.

TypeMismatch

Mismatched type, the Any does not contain the desired type.

Fields

has: String

The type URL contained in the Any.

want: String

The type URL of the desired type to extract from the Any.

Trait Implementations

impl Debug for AnyError

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

Formats the value using the given formatter.

impl Display for AnyError

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

Formats the value using the given formatter.

impl Error for AnyError

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.
