Enum ModelError 

#[non_exhaustive]
pub enum ModelError {
    Io(String),
    WrongFormat {
        expected: &'static str,
        detail: String,
    },
    Syntax {
        offset: usize,
        detail: String,
    },
    DanglingReference {
        from: EntityId,
        to: EntityId,
    },
    DuplicateId(EntityId),
    Write(String),
}

Errors from reading, writing, or querying a model.

Codec-specific detail is carried as a message rather than a nested error type: this crate must not depend on any codec, so it cannot name their error types.

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.

Io(String)

Underlying I/O failure.

WrongFormat

The bytes are not this format at all.

Fields

expected: &'static str

Format the codec expected.

detail: String

What was seen instead.

Syntax

Syntax error at a known location.

Fields

offset: usize

Byte offset into the source.

detail: String

What went wrong.

DanglingReference

An entity referenced an id that does not exist.

Fields

from: EntityId

The referring entity.

to: EntityId

The missing target.

DuplicateId(EntityId)

The same id was defined twice.

Write(String)

Serialization failed.

Trait Implementations

impl Debug for ModelError

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

Formats the value using the given formatter.

impl Display for ModelError

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

Formats the value using the given formatter.

impl Error for ModelError

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 From<StepError> for ModelError

fn from(error: StepError) -> ModelError

Converts to this type from the input type.
