Struct ConversionError 

pub struct ConversionError { /* private fields */ }

Error produced while converting a Protobuf message into a domain object.

Implementations

impl ConversionError

pub fn new(source: impl Error + Send + Sync + 'static) -> ConversionError

pub fn context(self, field: impl Into<String>) -> ConversionError

pub fn missing_field<T>(field_name: &'static str) -> ConversionError

where T: Message,

pub fn wrong_variant( expected: &'static str, actual: &'static str, ) -> ConversionError

Reports a oneof extraction mismatch using exact wire variant names.

The actual variant is added to the field path. No payload is decoded or verified when the requested variant does not match.

pub fn deserialization( entity: &'static str, source: impl Error + Send + Sync + 'static, ) -> ConversionError

pub fn message(message: impl Into<String>) -> ConversionError

pub fn with_source( message: impl Into<String>, source: impl Error + Send + Sync + 'static, ) -> ConversionError

pub fn into_status(self) -> Status

Converts this input conversion failure into a gRPC InvalidArgument status.

The message includes the field path and every source-chain level, even when a source’s Display omits its own cause. Deeper causes are separated by \ncaused by: ; a cause may appear more than once if an outer error already includes it in its display text. The original error is also retained as the status’s local source.

Available with the optional tonic feature, which enables std without transport.

Trait Implementations

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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.
