Function scylla::serialize::row::serialize_legacy_row
source · pub fn serialize_legacy_row<T>(
r: &T,
ctx: &RowSerializationContext<'_>,
writer: &mut RowWriter<'_>,
) -> Result<(), SerializationError>where
T: ValueList,Expand description
Serializes an object implementing ValueList by using the RowWriter
interface.
The function first serializes the value with ValueList::serialized, then
parses the result and serializes it again with given RowWriter. In case
or serialized values with names, they are converted to serialized values
without names, based on the information about the bind markers provided
in the RowSerializationContext.
It is a lazy and inefficient way to implement RowWriter via an existing
ValueList impl.
Returns an error if ValueList::serialized call failed or, in case of
named serialized values, some bind markers couldn’t be matched to a
named value.
See impl_serialize_row_via_value_list which generates a boilerplate
SerializeRow implementation that uses this function.
