[BUG] Compilation Fails on Latest Nightly

[HTGAzureX1212]

Description

When building the crate with the latest nightly, the compilation fails with 27 errors.

Prerequisites

• Rust version : rustc 1.51.0-nightly (d4e3570db 2021-02-01)
• lexical version: 0.7.4

All of them are E0308 and E0277

[HTGAzureX1212]

The compilation works on the nightly build on 2021-01-31.

Here is an example build: https://github.com/testcontainers/testcontainers-rs/runs/1811323780?check_suite_focus=true

[HTGAzureX1212]

It looks like <integer>::BITS has been stabilized in the standard library, therefore that Limb::BITS resolved into a u32 instead of usize.

Looks like rust nightly will revert the change until lexical-core can implement a suitable fix.
