Enum DataError 

pub enum DataError {
    NotANumber,
    Infinite,
    Negative,
}

Error returned when a streaming update receives invalid data.

The library distinguishes two failure categories:

• Data errors (NaN, Inf) → returned as Result<_, DataError>
• Programmer errors (wrong dimensions, out-of-range) → panic

The library makes no assumptions about the caller’s policy. Each system has different implications for bad data.

Variants

NotANumber

Input contained NaN.

Infinite

Input contained positive or negative infinity.

Negative

Input contained a negative value where non-negative was required.

Trait Implementations

impl Clone for DataError

fn clone(&self) -> DataError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DataError

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Eq for DataError

impl Error for DataError

Available on crate feature std only.

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 DataError

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