Enum ModelError

pub enum ModelError {
    Io(Error),
    UnrecognizedFormat,
    UnsupportedVersion {
        found: u16,
        newest: u16,

Something that went wrong while saving or loading a model.

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(Error)

The file could not be read or written.

UnrecognizedFormat

The data is not a model written by this library.

UnsupportedVersion

The model was written by a newer version of this library, in a format this version does not know.

Fields

found: u16

The version stored in the file.

newest: u16

The newest version this library reads, MODEL_FORMAT_VERSION.

Malformed

The data starts like a model but is truncated or corrupted.

Fields

reason: &'static str

What was wrong.

DimensionMismatch

The stored network has a different shape than the type asked for.

Fields

end: &'static str

Which end of the network mismatched.

expected: usize

The width required by the requested type.

found: usize

The width actually found in the file.

EmptyNetwork

The file decoded to a network with no layers at all.

InconsistentLayer

A stored layer does not fit with itself or with the layer before it, which means the file was corrupted or edited by hand.

Fields

layer: usize

The layer number, counting the input layer as 0.

reason: &'static str

What disagreed.

Trait Implementations

impl Debug for ModelError

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

Formats the value using the given formatter.

impl Display for ModelError

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

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<Error> for ModelError

fn from(source: Error) -> Self

Converts to this type from the input type.
