Enum RegistryError 

pub enum RegistryError {
    Parse {
        key: String,
        message: String,
    },
    Cycle {
        keys: Vec<String>,
    },
}

Errors surfaced when loading/compiling a registry — all caught at load time (not per node), so a bad user formula fails fast with a clear message.

Variants

Parse

A formula_cel failed to parse as CEL.

Fields

key: String

message: String

Cycle

The metric dependency graph has a cycle (a ← b ← a).

Fields

keys: Vec<String>

Trait Implementations

impl Debug for RegistryError

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

Formats the value using the given formatter.

impl Display for RegistryError

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

Formats the value using the given formatter.

impl Error for RegistryError

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.
