Building v0.8.1 fails with feature "postgres" enabled

[oleggtro]

Bug Description

On enabling the "postgres" feature building of the sqlx-postgres crate fails.

Minimal Reproduction

Add sqlx v0.8.1 with feature "postgres" enabled in your Cargo.toml and try building.

Info

• SQLx version: 0.8.1
• SQLx features enabled: ["postgres", "chrono", "macros", "migrate", "tls-rustls", "uuid", "derive", "runtime-tokio"]
• Database server and version: Postgres
• Operating system: macOS Sonoma 14.6.1
• rustc --version: rustc 1.79.0 (129f3b996 2024-06-10)

[oleggtro]

okay nevermind, building with rustc 1.80.1 succeeds.
It failed with some error having to to with some size_of::<>() function, I don't remember exactly.

So for anyone reading this: Try running rustup update to update your toolchain and then it should work fine.

[CommanderStorm]

The reason for this is that size_of was added to the prelude in 1.80.0

• Add size_of and size_of_val and align_of and align_of_val to the prelude rust-lang/rust#123168

Note

Relevant disclaimer about MSRV of sqlx.

Given that this is a quite simple fix, I think changing what #3457 has proposed is reasonable.

Yes. I did rustup update and the problem disappeared so I thought that sqlx should work on latest Rustc and there is no guarantee that sqlx will work on the older versions. Sorry for my confusion.
