Enum AttributeError 

pub enum AttributeError {
    UnknownAttribute(String),
    TypeMismatch {
        attribute: String,
        expected: String,
        actual: String,
    },
    Readonly(String),
}

Errors raised while dynamically reading or writing model attributes.

Variants

UnknownAttribute(String)

The attribute name does not exist on the model.

TypeMismatch

The provided value does not match the attribute’s expected type.

Fields

attribute: String

Name of the attribute that rejected the value.

expected: String

Human-readable description of the expected type.

actual: String

Human-readable description of the actual type.

Readonly(String)

The attribute exists but cannot be written through dynamic assignment.

Trait Implementations

impl Clone for AttributeError

fn clone(&self) -> AttributeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeError

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

Formats the value using the given formatter.

impl Display for AttributeError

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

Formats the value using the given formatter.

impl Error for AttributeError

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.

impl PartialEq for AttributeError

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

Tests for self and other values to be equal, and is used by ==.

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

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