Struct diesel_dynamic_schema::dynamic_value::Any

pub struct Any;

Expand description

A marker type used to indicate that the provided FromSql impl does handle any passed database value, independently from the actual value kind

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
