Enum MigrateError

        path: PathBuf,
        source: Error,
    },

    Unsupported {

    InvalidBackend(String),
}

All migration error variants.

Uses thiserror for idiomatic error definitions. Each variant carries enough context to be useful in CLI output (path, backend, underlying error).

Implementations

impl MigrateError

pub fn parse_backend(s: &str) -> Result<Backend, MigrateError>

Parse a backend name from a CLI string. Returns MigrateError::InvalidBackend if the string is not recognized.

Trait Implementations

impl Debug for MigrateError

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

Formats the value using the given formatter.

impl Display for MigrateError

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

Formats the value using the given formatter.

impl Error for MigrateError

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.
