Enum CombineError 

pub enum CombineError {
    TypeMismatch,
    HdrAddFailed,
}

Errors from combine_into / combine_hdr.

Variants

TypeMismatch

The two MetricPoints have different value variants (e.g., Counter vs Gauge). Indicates a programming error — only matching identity should ever combine.

HdrAddFailed

HDR add failed (typically because reservoirs have incompatible bounds).

Trait Implementations

impl Debug for CombineError

impl Eq for CombineError

impl Error for CombineError

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 CombineError

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

Equality operator ==.

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

Inequality operator !=.
