Struct ConversionError 

pub struct ConversionError { /* private fields */ }

Opaque error for protobuf-to-domain conversions.

Captures an underlying error plus an optional field path stack that describes which nested field caused the error (e.g. "block.header.account_root: value is not in range 0..MODULUS").

Always maps to tonic::Status::invalid_argument().

Implementations

impl ConversionError

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

Create a new ConversionError wrapping any error source.

pub fn context(self, field: &'static str) -> Self

Add field context to the error path.

Called from inner to outer, so the path accumulates in reverse (outermost field pushed last).

Use this to annotate errors from try_into() / try_from() where the underlying error has no knowledge of which field it originated from. Do not use it with missing_field which already embeds the field name in its message.

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

Create a “missing field” error for a protobuf message type T.

pub fn deserialization( entity: &'static str, source: DeserializationError, ) -> Self

Create a deserialization error for a named entity.

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

Create a ConversionError from an ad-hoc error message.

Trait Implementations

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

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.
