Trait block_tools::db::use_diesel::query_builder::BindCollector

pub trait BindCollector<DB> where
    DB: Backend, {
    pub fn push_bound_value<T, U>(
        &mut self, 
        bind: &U, 
        metadata_lookup: &<DB as TypeMetadata>::MetadataLookup
    ) -> Result<(), Error>
    where
        DB: HasSqlType<T>,
        U: ToSql<T, DB>;
}

A type which manages serializing bind parameters during query construction.

The only reason you would ever need to interact with this trait is if you are adding support for a new backend to Diesel. Plugins which are extending the query builder will use AstPass::push_bind_param instead.

Required methods

pub fn push_bound_value<T, U>(
    &mut self,
    bind: &U,
    metadata_lookup: &<DB as TypeMetadata>::MetadataLookup
) -> Result<(), Error> where
    DB: HasSqlType<T>,
    U: ToSql<T, DB>, 

Serializes the given bind value, and collects the result.
