Enum AutodiffError 

pub enum AutodiffError {
    ArityError {
        operation: &'static str,
        expected: usize,
        actual: usize,
    },
    EmptyGraph,
    IndexOutOfBounds {
        index: usize,
        max_index: usize,
    },
}

Errors that can occur during automatic differentiation computations.

Variants

ArityError

An operation received an incorrect number of arguments (specific arity error).

Fields

operation: &'static str

Name of the operation

expected: usize

Expected number of arguments

actual: usize

Actual number of arguments received

EmptyGraph

The computation graph is empty or invalid.

IndexOutOfBounds

An index references a non-existent value in the computation.

Fields

index: usize

The invalid index

max_index: usize

The maximum valid index

Implementations

impl AutodiffError

pub fn arity(operation: &'static str, expected: usize, actual: usize) -> Self

Create an ArityError for an operation with incorrect argument count.

pub fn check_arity( operation: &'static str, expected: usize, actual: usize, ) -> Result<(), AutodiffError>

Validate that an operation received the correct number of arguments.

Trait Implementations

impl Clone for AutodiffError

fn clone(&self) -> AutodiffError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AutodiffError

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

Formats the value using the given formatter.

impl Display for AutodiffError

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

Formats the value using the given formatter.

impl Error for AutodiffError

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 PartialEq for AutodiffError

fn eq(&self, other: &AutodiffError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
