Enum DistributedCheckError 

#[non_exhaustive]
pub enum DistributedCheckError {
    Fetch {
        what: &'static str,
        url: String,
        reason: String,
    },
    Mismatch(String),
}

Startup DDL-parity guard failed. Fatal: fix the config or the DDL.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fetch

A system-table query failed. The user opted into fail-fast verification, so connectivity problems fail startup too — distinguishably from mismatches.

Fields

what: &'static str

What was being fetched (cluster topology / table engine).

url: String

The endpoint URL queried.

reason: String

Human-readable cause.

Mismatch(String)

Config and cluster/DDL disagree (pre-formatted diff).

Trait Implementations

impl Debug for DistributedCheckError

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

Formats the value using the given formatter.

impl Display for DistributedCheckError

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

Formats the value using the given formatter.

impl Error for DistributedCheckError

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.
