Enum RegistryError 

#[non_exhaustive]
pub enum RegistryError {
    WrongKey,
    Failed {
        step: OpenStep,
        path: PathBuf,
        source: Box<dyn Error + Send + Sync>,
    },
    Recovery(TenantError),
}

Why the registry did not open: the key it was made under, or the step that failed, on which file, with the error underneath as its source, so a failure says its cause.

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.

WrongKey

server.sqlite was made under another master key.

Failed

step failed on path.

Fields

step: OpenStep

What was being done.

path: PathBuf

The file or directory it was done to.

source: Box<dyn Error + Send + Sync>

The error underneath.

Recovery(TenantError)

Start-up recovery failed.

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.

impl From<RegistryError> for TenantError

Every caller but the two that report it sees what TenantError can say.

fn from(e: RegistryError) -> TenantError

Converts to this type from the input type.
