Enum DotError 

pub enum DotError {
    ExactnessLost,
}

The dot product could not be computed exactly (see DotF64 docs).

Variants

ExactnessLost

At least one partial product a*b fell into the subnormal range (0 < |a·b| < 2⁻¹⁰²²), where the FMA two-product transformation can lose the low part. The accumulated value is still a high-quality result (each affected term’s error is below 2⁻¹⁰⁷⁴ · ½ulp of the subnormal grid), but bit-exactness of the mathematical dot product can no longer be guaranteed, so we tell you instead of pretending.

Trait Implementations

impl Eq for DotError

impl Error for DotError

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 DotError

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

Equality operator ==.

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

Inequality operator !=.
