Enum Error 

pub enum Error {
    Json(Error),
    Io(Error),
    UnsupportedArchitecture(String),
    UnsupportedActivation(String),
    UnsupportedFeature(String),
    WeightCountMismatch {
        expected: usize,
        found: usize,
    },
    ConfigTooLarge,
}

Errors produced when loading or building a NAM model.

Variants

Json(Error)

The .nam JSON could not be parsed.

Io(Error)

The file was read but its contents are not a valid/supported model.

UnsupportedArchitecture(String)

The model’s architecture field is not one this crate can run.

UnsupportedActivation(String)

A layer’s activation field names a function this crate does not implement.

UnsupportedFeature(String)

A .nam config uses a feature this crate does not yet implement (e.g. multi-channel input, a post-stack head with more than one output channel, mixed gating modes within one layer array, or an empty container). Rejected explicitly rather than silently mis-run — see the crate-level docs for the full list of supported and rejected features.

WeightCountMismatch

The flat weights array did not contain the number of values the config implies (corrupt file, or a config/weights mismatch).

Fields

expected: usize

Number of weights the config implies the file must contain.

found: usize

Number of weights actually present in the file’s flat weights array.

ConfigTooLarge

The config’s declared dimensions are so large that the implied weight count overflows usize, so the model cannot be built. Indicates a corrupt or adversarial file rather than a real capture.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
