Crate skippable_partialeq 

Ignore fields in PartialEq custom implementations.

Examples

use skippable_partialeq::SkippablePartialEq;
use chrono::{DateTime, TimeZone, Utc};
 
#[derive(Debug, SkippablePartialEq)]
#[exclude_suffix(at, date)]
pub struct Post {
    pub id: i64,
    pub content: String,
    pub author: i32,
    pub creation_date: DateTime<Utc>,
    pub updated_at: Option<DateTime<Utc>>,
}
 
assert_eq!(
    Post {
        id: 1,
        content: "test".to_string(),
        author: 1,
        creation_date: Utc.timestamp_millis_opt(1715017040672).unwrap(),
        updated_at: Some(Utc.timestamp_millis_opt(1715017020672).unwrap()),
    },
    Post {
        id: 1,
        content: "test".to_string(),
        author: 1,
        creation_date: Utc::now(),
        updated_at: Some(Utc::now()),
    }
) // true

You can also skip specific fields that do not follow a pattern using the #[skip] attribute above the fields you want to ignore:

use skippable_partialeq::SkippablePartialEq;
use chrono::{DateTime, TimeZone, Utc};
 
#[derive(Debug, SkippablePartialEq)]
pub struct Post {
    pub id: i64,
    pub content: String,
    pub author: i32,
    #[skip]
    pub creation_date: DateTime<Utc>,
}
assert_eq!(
    Post {
        id: 1,
        content: "test".to_string(),
        author: 1,
        creation_date: Utc.timestamp_millis_opt(1715017040672).unwrap(),
    },
    Post {
        id: 1,
        content: "test".to_string(),
        author: 1,
        creation_date: Utc::now(),
    }
)
