rustfmt configuration file

[ivanceras]

There is no rustfmt.tomlused in the code, except for .editorconfig
I'm trying to replicate the configurations used in substrate code to rustfmt.toml,

unstable_features = true
max_width = 100
# substrate devs uses hardtabs as convention
hard_tabs = true
# prevent reorder imports
reorder_imports = false
# prevent reorder of module declarations
reorder_modules = false
imports_layout = "Mixed"
use_small_heuristics = "Max"

but everytime I invoke cargo fmt there are a lot of changes to the code.
I'm curious to find out how the substrate devs are synchronizing their format configurations.

Hey, we don't use rustfmt in Substrate.

Here you can find our style guide.

Same, used to add one line in a .rs file and it changes more than 50+ lines after saving...one of a branch on my fork added 3 methods and 2 structs, it changes more than 5000+ lines, this is horrible.

To avoid unnecessary changes, I have to use TextEditor to apply the modification...

Appears rustfmt.toml can disable rustfmt entirely by saying ignore = ["/"] after rust-lang/rustfmt#3388, which causes errors on stable, but that's fine.

In case somebody using emacs, and have (rust-format-on-save t) working in the configuration.

(lambda ()
  (if (string-match "substrate" buffer-file-name)
    (rust-disable-format-on-save)))
