Struct EnvironmentOptions 

pub struct EnvironmentOptions { /* private fields */ }

Configures the WebView2 Environment, including the user data folder, the browser executable folder, additional browser command-line arguments, and the UI language. Build one with the fluent setters and pass it to Environment::with_options.

use windows_webview::EnvironmentOptions;

let options = EnvironmentOptions::new()
    .user_data_folder(r"C:\MyApp\WebView2")
    .additional_browser_arguments("--disable-features=msSmartScreenProtection")
    .language("en-US");

Implementations

impl EnvironmentOptions

pub fn new() -> Self

Creates options with all WebView2 defaults.

pub fn browser_executable_folder(self, value: impl Into<String>) -> Self

Sets the folder containing the WebView2 browser (Edge) binaries to use instead of the installed runtime.

pub fn user_data_folder(self, value: impl Into<String>) -> Self

Sets the folder where WebView2 stores its user data (cache, cookies, …).

pub fn additional_browser_arguments(self, value: impl Into<String>) -> Self

Sets additional command-line arguments passed to the browser process.
