Trait SerializableCopula 

Source 
pub trait SerializableCopula:
    Copula

Available on crate feature serde only.
Expand description

JSON serialization for copula models.

Implemented by the core copula types when the serde feature is enabled. A copula serializes to its parameters, and deserialization validates them through the type’s constructor, so invalid parameters are rejected.

§Examples

use copula_core::traits::SerializableCopula;
use copula_core::ClaytonCopula;

let copula = ClaytonCopula::new(2.0)?;
let json = copula.to_json()?;
assert_eq!(json, r#"{"theta":2.0}"#);

let restored = ClaytonCopula::from_json(&json)?;
assert_eq!(restored.to_json()?, json);

// Deserialization applies the same validation as `ClaytonCopula::new`.
assert!(ClaytonCopula::from_json(r#"{"theta":-1.0}"#).is_err());

Provided Methods§

Source

fn to_json(&self) -> Result<String>

Serialize the copula to a JSON string.

Source

fn from_json(json: &str) -> Result<Self>
where Self: Sized,

Deserialize a copula from a JSON string.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
