Trait Implementations

impl<ST> NotNull for Unsigned<ST>

impl<ST> SingleValue for Unsigned<ST>

impl<ST: QueryId> QueryId for Unsigned<ST>

[+]

type QueryId = Unsigned<<ST as QueryId>::QueryId>

A type which uniquely represents Self in a SQL query.

const HAS_STATIC_QUERY_ID: bool

HAS_STATIC_QUERY_ID: bool = <ST as QueryId>::HAS_STATIC_QUERY_ID && true

Can the SQL generated by Self be uniquely identified by its type?
