Serde Str

Documentation | Github | crates.io | libs.rs

A serde wrapper that simplifies (de)serializaton of data types using Display (as ToString::to_string(&self)) and FromStr as intermediataries.

Examples

use serde::{Serialize, Deserialize};
use std::net::IpAddr;

#[derive(Serialize, Deserialize)]
struct Struct {
	// By default IpAddr serializes the same in human-readable formats
	// like json. This forces the impl even for binary formats.
	//
	// More imporantly this is useful for types which don't have serde impl.
	#[serde(with = "serde_str")]
	ip: IpAddr,
}
#[derive(Serialize, Deserialize)]
struct Optional {
	// The above but handling null types
	#[serde(with = "serde_str::opt")]
	ip: Option<IpAddr>,
}
#[derive(Serialize, Deserialize)]
struct Empty {
	// The above but an empty string is a none-value
	#[serde(with = "serde_str::emp")]
	ip: Option<IpAddr>,
}
#[derive(Serialize, Deserialize)]
struct EmptyOptional {
	// The above but an empty string, null, or unspecified is a none-value.
	#[serde(with = "serde_str::emp", default)]
	ip: Option<IpAddr>,
}
