Struct diesel::query_builder::DebugQuery

source · [−]

pub struct DebugQuery<'a, T: 'a, DB> { /* private fields */ }

Expand description

A struct that implements fmt::Display and fmt::Debug to show the SQL representation of a query.

The Display implementation will be the exact query sent to the server, plus a comment with the values of the bind parameters. The Debug implementation is more structured, and able to be pretty printed.

See debug_query for usage examples.
