  = note: `-W clippy::many-single-char-names` implied by `-W clippy::pedantic`

Real output of Clippy 0.1.99 (Rust 1.99) on the example below. Names and line numbers in yours will differ.

Does it matter?

It’s hard to memorize what a variable means without a descriptive name.

Stricter lints with some false positives. Off by default; opt in with clippy::pedantic.

How to fix it

Clippy does not fix this one automatically. Change the code by hand:

Flagged

let (a, b, c, d, e, f, g) = (...);

Turn it off, or on

It is off by default. To use it, set it to warn or deny:

[lints.clippy]
many_single_char_names = "warn"

#![warn(clippy::many_single_char_names)]

cargo clippy -- -W clippy::many-single-char-names

The [lints] table needs Rust 1.74 or newer. In a workspace, put it under [workspace.lints.clippy] and add [lints] workspace = true to each member.

Settings in clippy.toml
