Enum fanova::FitError

#[non_exhaustive]pub enum FitError {
    EmptyRows,
    RowSizeMismatch,
    NonFiniteTarget,
}

Possible errors which could be returned by Fanove::fit method.

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.

EmptyRows

Features and target must have one or more rows.

RowSizeMismatch

Some of features or target have a different row count from others.

NonFiniteTarget

Target contains non finite numbers.

Trait Implementations

impl Clone for FitError

fn clone(&self) -> FitError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FitError

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

Formats the value using the given formatter.

impl Display for FitError

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

Formats the value using the given formatter.

impl Error for FitError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
