Struct ReadUncommitted 

pub struct ReadUncommitted;

Isolation::ReadUncommitted as a type, for the bound Opens sets.

Examples

use ruststream_sqlx_dialect::{
    Dialect, Isolation, Opening, Opens, Statement, StatementError, TableSpec, level,
};

/// SQL Server, a database without a built-in dialect.
#[derive(Debug)]
pub struct Mssql;

impl Dialect for Mssql {
    fn name(&self) -> &'static str {
        "mssql"
    }

    fn begin(&self, opening: Opening) -> Result<Option<&'static str>, StatementError> {
        match opening {
            Opening::Default => Ok(Some(
                "SET TRANSACTION ISOLATION LEVEL READ COMMITTED; BEGIN TRANSACTION",

            Opening::Isolation(Isolation::ReadUncommitted) => Ok(Some(
