Trait Implementations§

impl QueryMetadata<Any> for Mysql

fn row_metadata( _lookup: &mut Self::MetadataLookup, out: &mut Vec<Option<Self::TypeMetadata>>, )

The exact return value of this function is considered to be a backend specific implementation detail. You should not rely on those values if you not own the corresponding backend

impl QueryMetadata<Any> for Pg

fn row_metadata( _lookup: &mut Self::MetadataLookup, out: &mut Vec<Option<Self::TypeMetadata>>, )

The exact return value of this function is considered to be a backend specific implementation detail. You should not rely on those values if you not own the corresponding backend

impl QueryMetadata<Any> for Sqlite

fn row_metadata( _lookup: &mut Self::MetadataLookup, out: &mut Vec<Option<Self::TypeMetadata>>, )

The exact return value of this function is considered to be a backend specific implementation detail. You should not rely on those values if you not own the corresponding backend
