Struct EnvVarConfig 

pub struct EnvVarConfig { /* private fields */ }

Configuration provider that reads from environment variables.

This is the default configuration provider for WiseGate CLI. All values are cached at creation time using the global lazy statics.

Implements all composable configuration traits:

• RateLimitingProvider for rate limiting settings
• ProxyProvider for proxy behavior
• FilteringProvider for request filtering
• ConnectionProvider for connection limits

Example

use wisegate::config::EnvVarConfig;
use wisegate_core::RateLimitingProvider;

let config = EnvVarConfig::new();
println!("Max requests: {}", config.rate_limit_config().max_requests);

Implementations

impl EnvVarConfig

pub fn new() -> Self

Creates a new configuration provider from environment variables.

This triggers lazy initialization of all configuration values if they haven’t been accessed yet.

fn auth_realm(&self) -> &str

Returns the realm for WWW-Authenticate header.

fn bearer_token(&self) -> Option<&str>

Returns the bearer token, if configured.

fn forward_authorization_header(&self) -> bool

Whether to forward the Authorization header to the upstream service.

Returns true if Basic Auth is enabled (credentials configured).

fn is_bearer_auth_enabled(&self) -> bool

Returns true if Bearer Token auth is enabled.

fn is_auth_enabled(&self) -> bool

Returns true if any authentication is enabled.

impl Clone for EnvVarConfig

fn clone(&self) -> EnvVarConfig
