Enum SchemaConformanceError 

#[non_exhaustive]
pub enum SchemaConformanceError {
    Database(Error),
    UnsupportedPostgresVersion {
        required_major: u16,
        actual_server_version_num: i32,
    },
    Contract {
        version: u16,
        detail: String,
    },
}

Why a host database does not satisfy a canonical schema contract.

crate::assert_runtime_schema_v2_compatible reports version 2 in its Self::Contract diagnostic. Database failures include inability to begin or commit the read-only catalog snapshot.

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.

impl Error for SchemaConformanceError

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<Error> for SchemaConformanceError

fn from(source: Error) -> Self

Converts to this type from the input type.
