Trait ModelValidate 

pub trait ModelValidate: Sized {
    // Required method
    fn model_validate(
        input: impl Into<ValidateInput>,
        options: ValidateOptions,
    ) -> ValidateResult<Self>;

    // Provided methods
    fn model_validate_json(json: &str) -> ValidateResult<Self> { ... }
    fn model_validate_dict(dict: HashMap<String, Value>) -> ValidateResult<Self> { ... }
}

Trait for models that support model_validate().

This is typically implemented via derive macro or blanket impl for models that implement Deserialize.

Required Methods

fn model_validate( input: impl Into<ValidateInput>, options: ValidateOptions, ) -> ValidateResult<Self>

Create and validate a model from input.

Arguments

• input - The input to validate (Dict, Json, or JsonValue)
• options - Validation options

Returns

The validated model or validation errors.

Example

use sqlmodel_core::validate::{ModelValidate, ValidateInput, ValidateOptions};

let user = User::model_validate(
    r#"{"name": "Alice", "age": 30}"#,
    ValidateOptions::default()
)?;

Provided Methods

fn model_validate_json(json: &str) -> ValidateResult<Self>

Create and validate a model from JSON string with default options.

fn model_validate_dict(dict: HashMap<String, Value>) -> ValidateResult<Self>

Create and validate a model from a HashMap with default options.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<T: DeserializeOwned> ModelValidate for T

Blanket implementation of ModelValidate for types that implement DeserializeOwned.

This provides model_validate() for any model that can be deserialized from JSON.
