[][src]Struct diesel::prelude::SqliteConnection

pub struct SqliteConnection { /* fields omitted */ }

Connections for the SQLite backend. Unlike other backends, "connection URLs" for SQLite are file paths, URIs, or special identifiers like :memory:.

Methods

impl SqliteConnection[src]

pub fn immediate_transaction<T, E, F>(&self, f: F) -> Result<T, E> where
    F: FnOnce() -> Result<T, E>,
    E: From<Error>, 
[src]

Run a transaction with BEGIN IMMEDIATE

This method will return an error if a transaction is already open.

Example

conn.immediate_transaction(|| {
    // Do stuff in a transaction
    Ok(())
})

pub fn exclusive_transaction<T, E, F>(&self, f: F) -> Result<T, E> where
    F: FnOnce() -> Result<T, E>,
    E: From<Error>, 
[src]

Run a transaction with BEGIN EXCLUSIVE

This method will return an error if a transaction is already open.

Example

conn.exclusive_transaction(|| {
    // Do stuff in a transaction
    Ok(())
})
