Crate serde_tuplex 

Tuple serialization and lenient numeric parsing for serde.

Features

• Tuple - Serialize/deserialize as [1,2] instead of {"x":1,"y":2}
• Lenient - Accept both 123 and "123" for numeric fields
• TupleLenient - Combine both

Examples

use serde_tuplex::{Lenient, Tuple, TupleLenient};

#[derive(Lenient)]
struct User {
    id: u64,        // Accepts 100 or "100"
    name: String,
}

#[derive(Tuple)]
struct Point { x: i32, y: i32 }  // JSON: [10,20]

#[derive(TupleLenient)]
struct Data { count: u64 }  // Both features

Manual control

use serde::Deserialize;
use serde_tuplex::{lenient, lenient_option};

#[derive(Deserialize)]
struct Config {
    #[serde(deserialize_with = "lenient")]
    timeout: u64,
     
    // For Option<T>, add 'default' to handle missing fields
    #[serde(deserialize_with = "lenient_option", default)]
    retry: Option<u32>,
     
    port: u16,  // Strict
}

Use #[serde_tuplex(skip)] to disable lenient parsing:

use serde_tuplex::Lenient;

#[derive(Lenient)]
struct Mixed {
    lenient: u64,
    #[serde_tuplex(skip)]
    strict: u32,
}

Functions

lenient

Deserialize numeric values that accept both numbers and strings.

lenient_option

Deserialize Option<T> with lenient parsing for numeric values.

Derive Macros

Lenient

Accept both 123 and "123" for numeric fields.

Tuple

Serialize/deserialize structs as tuples: [1,2] instead of {"x":1,"y":2}.

TupleLenient
