assignment

What it does

Checks for consistency of assignment operator.

Why is this bad?

In most cases using = and <- is equivalent. Some very popular packages use = without problems. This rule only ensures the consistency of the assignment operator in a project.

Note that Jarl doesn’t force you to use <- as assignment operator, it simply uses it as default. To use = as the preferred operator:

• in the CLI (temporary change), use --assignment-op "=";
• in jarl.toml (permanent change): set assignment = "=".

Example

x = "a"

Use instead:

x <- "a"
