Error

Enum Error 

Source
pub enum Error {
    Sqlite(i32, Option<String>),
    Utf8Error(Utf8Error),
    NulError(NulError),
    VersionNotSatisfied(c_int),
    Module(String),
    NoChange,
}

Variants§

§

Sqlite(i32, Option<String>)

An error returned by SQLite.

§

Utf8Error(Utf8Error)

A string received from SQLite contains invalid UTF-8, and cannot be converted to a &str.

§

NulError(NulError)

A string being passed from Rust to SQLite contained an interior nul byte.

§

VersionNotSatisfied(c_int)

Caused by an attempt to use an API that is not supported in the current version of SQLite.

§

Module(String)

An arbitrary string error message. This is never generated by SQLite or sqlite3_ext, but can be used by consumers of this crate to cause SQLite to fail with a particular error message.

§

NoChange

The result was not necessary to produce because it is an unchanged column in an UPDATE operation. See ValueRef::nochange for details.

Implementations§

Source§

impl Error

Source

pub fn from_sqlite(rc: i32) -> Result<()>

Convert the return of an SQLite function into a Result<()>. This method properly handles the non-error result codes (SQLITE_OK, SQLITE_ROW, and SQLITE_DONE).

Source

pub fn from_sqlite_desc( rc: i32, guard: SQLiteMutexGuard<'_, Connection>, ) -> Result<()>

Convert the return of an SQLite function into a Result<()>, with a complete error message. This method is similar to from_sqlite, except that it retrieves the full error message from SQLite in addition to the error code.

Source

pub unsafe fn from_sqlite_desc_unchecked( rc: i32, conn: *mut sqlite3, ) -> Result<()>

Equivalent to from_sqlite_desc, but without requiring a lock on the database.

§Safety

This method is safe, however it may produce incorrect results if called while a lock on the SQLite database is not held.
