Lint that a version requirement is lower than what is currently in `Cargo.lock`

[epage]

What it does

Lint when a dependency version requirement is lower than the resolved dependencies version.

Advantage

• Low effort way of ensuring version requirements are not too low

Drawbacks

• Someone can verify their version requirements a different way
• Even if someone is using this for helping with version requiirements, there are times where they want to raise the version requirements (e.g. testing latest)

Example

[dependencies]
serde = "1.0.0"

Could be written as:

[dependencies]
serde = "1.0.216"
