# [−][src]Trait diesel::prelude::Expression

Represents a typed fragment of SQL.

Apps should not need to implement this type directly, but it may be common
to use this in where clauses. Libraries should consider using
`infix_operator!`

or
`postfix_operator!`

instead of
implementing this directly.

## Associated Types
