Code formatting with rustfmt.toml config

[kamuik16]

Description

We can add a rustfmt.toml file to the repo and use some of the nightly features like

reorder_imports  = true
imports_granularity = "Crate"
format_code_in_doc_comments = true

Read more about these configs in here.

Motivation

Highly improved code formatting and readability.
Formatting imports.
Formatting the code in doc as well.
Example: reth - rustfmt.toml

Current Implementation

This:

pub use self::behaviour::{Behaviour, Event, MessageAuthenticity};
pub use self::config::{Config, ConfigBuilder, ValidationMode, Version};
pub use self::error::{ConfigBuilderError, PublishError, SubscriptionError, ValidationError};
pub use self::metrics::Config as MetricsConfig;
pub use self::peer_score::{
    score_parameter_decay, score_parameter_decay_with_base, PeerScoreParams, PeerScoreThresholds,
    TopicScoreParams,
};
pub use self::subscription_filter::{
    AllowAllSubscriptionFilter, CallbackSubscriptionFilter, CombinedSubscriptionFilters,
    MaxCountSubscriptionFilter, RegexSubscriptionFilter, TopicSubscriptionFilter,
    WhitelistSubscriptionFilter,
};
pub use self::topic::{Hasher, Topic, TopicHash};
pub use self::transform::{DataTransform, IdentityTransform};
pub use self::types::{Message, MessageAcceptance, MessageId, RawMessage};

will look like this:

pub use self::{
    behaviour::{Behaviour, Event, MessageAuthenticity},
    config::{Config, ConfigBuilder, ValidationMode, Version},
    error::{ConfigBuilderError, PublishError, SubscriptionError, ValidationError},
    metrics::Config as MetricsConfig,
    peer_score::{
        score_parameter_decay, score_parameter_decay_with_base, PeerScoreParams,
        PeerScoreThresholds, TopicScoreParams,
    },
    subscription_filter::{
        AllowAllSubscriptionFilter, CallbackSubscriptionFilter, CombinedSubscriptionFilters,
        MaxCountSubscriptionFilter, RegexSubscriptionFilter, TopicSubscriptionFilter,
        WhitelistSubscriptionFilter,
    },
    topic::{Hasher, Topic, TopicHash},
    transform::{DataTransform, IdentityTransform},
    types::{Message, MessageAcceptance, MessageId, RawMessage},
};

This is just one of the example across repo.

Are you planning to do it yourself in a pull request ?

Yes

Curios to know the opinions of the maintainers here :)
