Enum LogarithmRealInputErrors 

pub enum LogarithmRealInputErrors<RawReal: RawRealTrait> {
    NegativeArgument {
        value: RawReal,
        backtrace: Backtrace,
    },
    ZeroArgument {
        backtrace: Backtrace,
    },
    InvalidArgument {
        source: <RawReal as RawScalarTrait>::ValidationErrors,
    },
}

Errors that can occur when computing the logarithm of a real number.

This enum represents the possible errors that can occur when computing the logarithm of a real number. It includes errors for invalid arguments and other validation errors.

Type Parameters

• RawReal: A type that implements the RawRealTrait trait. This type parameter is used to specify the numeric type for the computation and its associated raw error type <RawReal as RawScalarTrait>::ValidationErrors.

Variants

• NegativeArgument: Indicates that the argument of the function is negative, which is not allowed for real logarithms. This variant includes the value that is out of the domain and a backtrace.
• ZeroArgument: Indicates that the argument of the function is zero, which is not allowed for real logarithms. This variant includes a backtrace.
• InvalidArgument: Indicates that the argument of the function is invalid. This variant includes the source error that occurred during validation.

Variants

NegativeArgument

The argument of the function is negative.

This variant indicates that the argument of the function is negative, which is not allowed for real logarithms. It includes the value that is out of the domain and a backtrace.

Fields

value: RawReal

The value that is out of the domain.

backtrace: Backtrace

ZeroArgument

The argument of the function is zero.

This variant indicates that the argument of the function is zero, which is not allowed for real logarithms. It includes a backtrace.

Fields

backtrace: Backtrace

InvalidArgument

The argument of the function is invalid.

This variant indicates that the argument of the function is invalid. It includes the source error that occurred during validation.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The source error that occurred during validation.

Trait Implementations

impl<RawReal: RawRealTrait> Error for LogarithmRealInputErrors<RawReal>

where <RawReal as RawScalarTrait>::ValidationErrors: Error + 'static, Self: Debug + Display,

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

Returns the lower-level source of this error, if any.

fn provide<'_request>(&'_request self, request: &mut Request<'_request>)

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

Provides type-based access to context intended for error reports.

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
