Variants

Validation

Validation failed for a specific field.

Fields

field: String

reason: String

NotFound

No row with the given id was found.

Fields

id: String

Schema(String)

schema.yaml could not be parsed.

Storage(Error)

A SQLite storage error occurred.

Io(Error)

A filesystem I/O error occurred.

Config(String)

An environment-variable or .env configuration error occurred.

TableNotFound

The requested table is not mounted in the registry.

Fields

table: String

TableRequired

Multi-table mode requires a table argument that was omitted.

SchemaExists

A schema file already exists for the given table.

Fields

table: String

Backup(String)

A backup I/O or SQLite backup operation failed.

Snapshot(String)

A snapshot I/O or SQLite snapshot operation failed.

BatchAborted

schema_batch was aborted because one of its ops failed.

Fields

op_index: usize

reason: String

MaterializeDestRelative

The destination path supplied to row_materialize is not absolute.

Fields

path: String

MaterializeDestInvalid

The destination path is absolute but invalid for another reason.

Fields

path: String

reason: String

MaterializeIo(String)

A filesystem I/O error occurred during row_materialize.

MaterializeSha256(String)

SHA-256 computation failed during row_materialize.

MaterializeRowNotFound

The row id specified in a ById selector was not found.

Fields

id: String

MaterializeEmptyResult

A ByFilter selector matched zero rows and ignore_empty is false.

MaterializeFormatError(String)

Serialization to the requested output format failed.

MaterializeFieldUnknown

A projected field name is not present in the table schema.

Fields

field: String

MaterializeInvalidParam

row_materialize parameters are structurally inconsistent.

Fields

field: String

reason: String

AliasNotFound

No query alias with the given name was found in _aliases.

Fields

name: String

AliasAlreadyExists

An alias with the given name already exists in _aliases.

Fields

name: String

AliasParamsRequired

alias_run was called without params but the alias requires parameter injection (its params_schema is non-null).

Fields

name: String

AliasTemplateError(String)

MiniJinja template rendering failed during alias_run.

AmbiguousId

An id prefix matched more than one row.

Fields

id_prefix: String

Implementations

impl MiniAppError

pub fn code(&self) -> &'static str

Returns the machine-readable error code for this variant.

Trait Implementations

impl Debug for MiniAppError

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

Formats the value using the given formatter.

impl Display for MiniAppError

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

Formats the value using the given formatter.

impl Error for MiniAppError

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 MiniAppError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for MiniAppError

fn from(source: Error) -> Self
