Crate vld_dioxus 

vld-dioxus — Dioxus integration for the vld validation library

Shared validation for Dioxus server functions and WASM clients. Define validation rules once, use them on both the server and the browser.

Zero dependency on dioxus — works with any Dioxus version (0.5, 0.6, 0.7+). Compatible with WASM and native targets.

Key Features

Feature	Description
validate_args!	Inline validation of server function arguments
validate / validate_value	Validate a serializable value against a schema
check_field	Single-field validation for reactive UI
check_all_fields	Multi-field validation returning per-field errors
VldServerError	Serializable error type for server→client error transport

Quick Example

// Shared validation rules (used on server AND client)
fn name_schema() -> vld::primitives::ZString { vld::string().min(2).max(50) }
fn email_schema() -> vld::primitives::ZString { vld::string().email() }

// Server function
#[server]
async fn create_user(name: String, email: String) -> Result<(), ServerFnError> {
    vld_dioxus::validate_args! {
        name  => name_schema(),
        email => email_schema(),
    }.map_err(|e| ServerFnError::new(e.to_string()))?;
    Ok(())
}

// Client component (reactive validation)
#[component]
fn CreateUserForm() -> Element {
    let mut name = use_signal(String::new);
    let name_err = use_memo(move || {
        vld_dioxus::check_field(&name(), &name_schema())
    });
    // ... render form with error display
}
