Enum EagerRecordError 

pub enum EagerRecordError {
    CountMismatch {
        field: &'static str,
        expected: usize,
        actual: usize,
    },
    KeyMismatch {
        field: &'static str,
        index: usize,
    },
    TooManyOutputs {
        actual: usize,
        max: usize,
    },
}

Error returned when eager graph recording receives inconsistent metadata.

These errors describe caller-visible recording contract violations. AD rule failures during linearization are still reported as crate::ADRuleError.

Variants

CountMismatch

A caller supplied a slice whose length must match graph metadata.

Fields

field: &'static str

Name of the validated field.

expected: usize

Required length.

actual: usize

Supplied length.

KeyMismatch

A caller supplied keys in an order that does not match the graph.

Fields

field: &'static str

Name of the validated field.

index: usize

Mismatching slot.

TooManyOutputs

The graph has more outputs than eager tracing can address.

Fields

actual: usize

Supplied output count.

max: usize

Maximum accepted output count.

Trait Implementations

impl Clone for EagerRecordError

fn clone(&self) -> EagerRecordError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EagerRecordError

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

Formats the value using the given formatter.

impl Display for EagerRecordError

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

Formats the value using the given formatter.

impl Error for EagerRecordError

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 EagerRecordError

fn eq(&self, other: &EagerRecordError) -> 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.
