Importing sqlx as .toml dependency failed

[Flemming-DC]

Bug Description

I cannot include sqlx in a blank rust project due to "use of unstable library feature 'error_in_core'", unless I pick a really old version namely sqlx=0.3.5.

Info

• SQLx version: 0.8.2 (amonst other versions)
• SQLx features enabled: None, just sqlx = "0.8.2"
• Database server and version: none, I couldn't get that far. It cannot even import
• Operating system: Windows 11
• rustc --version: rustc 1.77.2 (25ef9e3d8 2024-04-09)

Minimal Reproduction

run cargo new --lib project_name and add sqlx = "0.8.2" to dependencies. Upon saving the toml, then you should get an error. Here is my toml.

[package]
name = "liber"
version = "0.1.0"
edition = "2021"

[dependencies]
sqlx = "0.8.2"

Here is the error message.
Running cargo test --no-run --lib --package=liber --message-format=json --color=always...

This bug disappears, when updagrading to the latest stable version of rust. XD
rustc 1.83.0 (90b35a623 2024-11-26)

Perhaps the sqlx readme should specify compatible rust versions?
Anyhow, for me the problem is solved.
