Add SqliteTypedQueryBuilder for exact type mapping

[Perksey]

PR Info

• Related to (doesn’t necessarily close) BIGINT PRIMARY KEY AUTOINCREMENT in SQLite #689

New Features

Adds customizable type mapping to ensure that the exact type can be used on SQLite if the user needs it.

Bug Fixes

Provides the ability for the user to enable BigUnsigned PRIMARY KEY AUTOINCREMENT.

Breaking Changes

I’ve done my best to avoid any breaking changes. This is done by introducing a SqliteTypedQueryBuilder and implementing a SqliteBuilderVariant trait on both builders to deduplicate the code.

Changes

I was hesitant to add a blanket implementation of sea-query types on T where T is a SqliteBuilderVariant, as this would definitely cause future problems, either here or downstream. Therefore, I’ve implemented a sqlite_impl macro which will repeat the implementation for both SqliteTypedQueryBuilder and SqliteQueryBuilder.

I forgot about the need of PhantomData when I originally proposed this, and this can’t be done in a non-breaking manor without separate types.

[Perksey]

This can close #689 but discussion is needed for whether we actually want to special case BIGINT AUTOINCREMENT on the default mapper.

@tyt2y3 ready for review, recommend filtering out whitespace changes

That's a very throughout comment section haha

[tyt2y3]

It looks pretty good.

My only hope is to have a prettier macro that can do the following:

#[impl_many]
impl T for A, B {
    fn method() {}
}

// which would:
impl T for A { .. }
impl T for B { .. }

that would create no doubt about what the sqlite_impl would do.

https://docs.rs/duplicate/latest/duplicate/attr.duplicate_item.html seems to be a pretty good one, do you have other suggestions?

[Perksey]

I couldn't find any macros that would support adding a generic parameter for one of the alternate selves, and attempting to make one did not go well!

[tyt2y3]

Alternatively, may be we can implement only a subset of the traits?

Sorry for the boomerang, but we've now decided to use feature flags for certain options. I'll add a flag
