Enum ModelSetError 

#[non_exhaustive]
pub enum ModelSetError {
    DuplicateId {
        id: String,
        existing: Box<ModelSource>,
        added: Box<ModelSource>,
    },
    InvalidId {
        id: String,
        reason: &'static str,
    },
}

Reason a model set rejects an entry.

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.

DuplicateId

The set already holds a model with this id.

Fields

id: String

Id the two entries share.

existing: Box<ModelSource>

Source of the entry the set holds.

added: Box<ModelSource>

Source of the rejected entry.

InvalidId

The id is outside the model id grammar.

Fields

id: String

Id the entry declares.

reason: &'static str

Clause saying how id breaks the grammar, such as “is empty”.

Trait Implementations

impl Debug for ModelSetError

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

Formats the value using the given formatter.

impl Display for ModelSetError

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

Formats the value using the given formatter.

impl Error for ModelSetError

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.
