Enum prost_reflect::SetFieldError

pub enum SetFieldError {
    NotFound,
    InvalidType {
        field: FieldDescriptor,
        value: Value,
    },
}

Error type returned by DynamicMessage::try_set_field().

Variants

NotFound

The field was not found.

InvalidType

The value type was not compatible with the field type (see Value::is_valid_for_field).

Fields

field: FieldDescriptor

The descriptor for the field which could not be set.

value: Value

The invalid value.

Trait Implementations

impl Clone for SetFieldError

fn clone(&self) -> SetFieldError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SetFieldError

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

Formats the value using the given formatter.

impl Display for SetFieldError

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

Formats the value using the given formatter.

impl Error for SetFieldError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.

impl PartialEq for SetFieldError

fn eq(&self, other: &SetFieldError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
