Trait rorm_sql::conditional::BuildCondition

pub trait BuildCondition<'a>: 'a {
    fn build_to_writer(
        &self,
        writer: &mut impl Write,
        dialect: DBImpl,
        lookup: &mut Vec<Value<'a>>
    ) -> Result<(), Error>;

    fn build(&self, dialect: DBImpl, lookup: &mut Vec<Value<'a>>) -> String { ... }
}

Trait implementing constructing sql queries from a condition tree.

This trait auto implements build which has a simpler api from the more complex build_to_writer.

Required Methods

fn build_to_writer(
    &self,
    writer: &mut impl Write,
    dialect: DBImpl,
    lookup: &mut Vec<Value<'a>>
) -> Result<(), Error>

This method is used to convert a condition to SQL without allocating a dedicated string.

Provided Methods

fn build(&self, dialect: DBImpl, lookup: &mut Vec<Value<'a>>) -> String
