ViewDef

Struct ViewDef 

Source
pub struct ViewDef {
    pub name: &'static str,
    pub definition: Option<&'static str>,
    pub is_existing: bool,
    pub error: Option<&'static str>,
}
Expand description

Const-friendly view definition

§Examples

use drizzle_types::sqlite::ddl::ViewDef;

const VIEW: ViewDef = ViewDef::new("active_users")
    .definition("SELECT * FROM users WHERE active = 1");

Fields§

§name: &'static str

View name

§definition: Option<&'static str>

View definition (AS SELECT …)

§is_existing: bool

Whether this is an existing view (not managed by drizzle)

§error: Option<&'static str>

Error message if the view failed to parse/validate
