Trait Pragma 

pub trait Pragma: Sized {
    type Scope: PragmaScope;

    const NAME: &'static str;
}

Available on crate feature __sqlite-shared only.

A pragma, named by NAME and scoped by Scope.

Required Associated Constants

const NAME: &'static str

The pragma name, written into the SQL unquoted.

A name that is empty or holds anything but ASCII letters, digits and underscores fails with Error::QueryBuilderError before reaching SQLite. Naming a pragma SQLite knows is up to the implementer, since SQLite ignores unknown ones.

Required Associated Types

type Scope: PragmaScope

PerSchema or PerConnection.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
