Enum SqlError 

pub enum SqlError {
    Parse {
        message: String,
        location: ErrorLocation,
        code: &'static str,
    },
    Plan {
        message: String,
        location: ErrorLocation,
        code: &'static str,
    },
    Execution {
        message: String,
        code: &'static str,
    },
    Storage {
        message: String,
        code: &'static str,
        source: Option<Error>,
    },
    Catalog {
        message: String,
        location: ErrorLocation,
        code: &'static str,
    },
}

統一 SQL エラー型（公開 API）。

Examples

use alopex_sql::SqlError;
use alopex_sql::StorageError;

let err = SqlError::from(StorageError::TransactionConflict);
assert_eq!(err.code(), "ALOPEX-S001");

Implementations

impl SqlError

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

エラーコード（例: ALOPEX-C001）。

pub fn message(&self) -> &str

ユーザー向けメッセージ（位置情報は含めない）。

pub fn location(&self) -> ErrorLocation

位置情報（未知の場合は { line: 0, column: 0 }）。

pub fn message_with_location(&self) -> String

span 情報付きメッセージを生成する（位置情報がない場合は位置部分を省略）。

Trait Implementations

impl Debug for SqlError

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

Formats the value using the given formatter.

impl Display for SqlError

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

Formats the value using the given formatter.

impl Error for SqlError

fn source(&self) -> Option<&(dyn StdError + '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.
