Enum Exec 

pub enum Exec<'a> {
    SqlitePool(&'a Pool<Sqlite>),
    SqliteConn(&'a mut SqliteConnection),
    PgPool(&'a Pool<Postgres>),
    PgConn(&'a mut PgConnection),
}

Where a statement is about to run.

Built through Into, so a call site passes a &Database, a transaction’s connection or a bare pool and the enum is an implementation detail.

Variants

SqlitePool(&'a Pool<Sqlite>)

SqliteConn(&'a mut SqliteConnection)

PgPool(&'a Pool<Postgres>)

PgConn(&'a mut PgConnection)

Implementations

impl Exec<'_>

pub fn dialect(&self) -> Dialect

Which dialect this will speak.

pub fn reborrow(&mut self) -> Exec<'_>

Borrows this executor again, for a caller that runs two statements.

An Exec owns a &mut connection, so it cannot be Copy; a function handed one and issuing more than one statement reborrows instead.

Trait Implementations

impl<'a> From<&'a Arc<Database>> for Exec<'a>

Most callers outside this crate hold the database behind an Arc, so a statement takes one without being handed &*db at every site.

fn from(database: &'a Arc<Database>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Database> for Exec<'a>

fn from(database: &'a Database) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Pool<Postgres>> for Exec<'a>

fn from(pool: &'a Pool<Postgres>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a Pool<Sqlite>> for Exec<'a>

fn from(pool: &'a Pool<Sqlite>) -> Self

Converts to this type from the input type.

impl<'a> From<&'a mut PgConnection> for Exec<'a>

fn from(conn: &'a mut PgConnection) -> Self

Converts to this type from the input type.

impl<'a> From<&'a mut SqliteConnection> for Exec<'a>

fn from(conn: &'a mut SqliteConnection) -> Self

Converts to this type from the input type.
