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.

Io(Error)

ManifestMissing

ManifestParse(String)

UnsupportedManifestVersion

Fields

found: u32

InvalidFileName(String)

DuplicateEntry

Fields

version: u32

file: String

OrphanMigration

Fields

path: String

MissingFile

Fields

version: u32

file: String

ChecksumDrift

Fields

version: u32

file: String

MissingDown

Fields

version: u32

file: String

InvalidIdentifier(String)

SetupFailed

Fields

file: String

source: Error

Sqlx(Error)

PoolTooSmall

The pool must have at least 2 connections: one is reserved for the advisory lock.

AppliedButMissing

An applied migration (present in the tracking table) is no longer on disk or in the manifest. Silently skipping it would bypass the integrity guard — surface it as an explicit error so operators notice the tampered or deleted migration file.

Fields

version: u32

file: String

Explorer(String)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
