view_proc!() { /* proc-macro */ }Expand description
Specifies that a view exists, and what fields it has. This will create a
new public module, with the same name, as the name of the view. In this
module, you will find a unit struct named view, and a unit struct with the
name of each field.
The macro and the generated code closely mirror the table! macro.
By default, this allows a maximum of 32 columns per view.
You can increase this limit to 64 by enabling the 64-column-tables feature.
You can increase it to 128 by enabling the 128-column-tables feature.
You can decrease it to 16 columns,
which improves compilation time,
by disabling the default features of Diesel.
Note that enabling 64 column tables or larger will substantially increase
the compile time of Diesel.
§Example usage
diesel::view! {
users {
name -> VarChar,
favorite_color -> Nullable<VarChar>,
}
}If you are using types that aren’t from Diesel’s core types, you can specify which types to import.
diesel::view! {
use diesel::sql_types::*;
use diesel_full_text_search::*;
posts {
title -> Text,
keywords -> TsVector,
}
}If you want to add documentation to the generated code, you can use the following syntax:
diesel::view! {
/// The table containing all blog posts
posts {
/// The post's title
title -> Text,
}
}If you have a column with the same name as a Rust reserved keyword, you can use
the sql_name attribute like this:
diesel::view! {
posts {
/// This column is named `mytype` but references the table `type` column.
#[sql_name = "type"]
mytype -> Text,
}
}This module will also contain several helper types:
§dsl
This simply re-exports the view, renamed to the same name as the module,
and each of the columns. This is useful to glob import when you’re dealing
primarily with one table, to allow writing users.filter(name.eq("Sean"))
instead of users::table.filter(users::name.eq("Sean")).
§all_columns
A constant will be assigned called all_columns. This is what will be
selected if you don’t otherwise specify a select clause. It’s type will be
view::AllColumns. You can also get this value from the
QueryRelation::all_columns function.
§star
This will be the qualified “star” expression for this view (e.g.
users.*). Internally, we read columns by index, not by name, so this
column is not safe to read data out of, and it has had its SQL type set to
() to prevent accidentally using it as such. It is sometimes useful for
counting statements, however. It can also be accessed through the Table.star()
method.
§SqlType
A type alias called SqlType will be created. It will be the SQL type of
all_columns. The SQL type is needed for things like returning boxed
queries.

Expanded code might use diesel internal API's and is only shown for educational purpose
The macro expands the input to the following Rust code:
