Enum CatalogError 

#[non_exhaustive]
pub enum CatalogError {
    UnknownId {
        family: IdFamily,
        id: u64,
    },
    UnknownName {
        kind: &'static str,
        name: String,
    },
    DuplicateName,
    DuplicateId,
    SchemaConflict {
        name: String,
        reason: &'static str,
    },
}

Errors from catalog identity: canonical ids, catalog names, and declared schema shapes.

Performance

Formatting is O(message length).

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.

UnknownId

A referenced canonical id is not present.

Fields

family: IdFamily

Id family that was looked up.

id: u64

Raw canonical id value that was absent.

UnknownName

A catalog name was not found in a bound schema.

Fields

kind: &'static str

The kind of catalog entry (for example "role" or "property key").

name: String

The name that was not found.

DuplicateName

Duplicate catalog name or ID.

DuplicateId

Duplicate canonical ID.

SchemaConflict

A declared schema item conflicts with an existing catalog entry.

Fields

name: String

The conflicting catalog name.

reason: &'static str

Deterministic reason the declaration conflicts with the catalog.

Trait Implementations

impl Debug for CatalogError

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

Formats the value using the given formatter.

impl Display for CatalogError

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

Formats the value using the given formatter.

impl Error for CatalogError

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 From<CatalogError> for DbError

fn from(error: CatalogError) -> Self

Converts to this type from the input type.
