Struct AppConfig 

pub struct AppConfig<ConfigExt = Empty> {
    pub host: IpAddr,
    pub port: u16,
    pub observability_cfg: ObservabilityConfig,
    pub management_cfg: ManagementConfig,
    pub private: ConfigExt,
    pub worker_guard: Option<WorkerGuard>,
}

AppConfig reads and saves application configuration from different sources

Fields

host: IpAddr

host address where to start Application

port: u16

When serialized uses <PREFIX>_PORT or <PREFIX>_SERVER_PORT names. <PREFIX>_SERVER_PORT has higher priority.

observability_cfg: ObservabilityConfig

configuration for logs and traces

management_cfg: ManagementConfig

configures management endpoints

private: ConfigExt

field for each application specific configuration

worker_guard: Option<WorkerGuard>

Why it is here read more: [https://docs.rs/tracing-appender/latest/tracing_appender/non_blocking/struct.WorkerGuard.html] This one will not be cloned and will be set to None in clone.

Implementations

impl<ConfigExt> AppConfig<ConfigExt>

pub fn builder() -> AppConfigBuilder<ConfigExt>

Creates AppConfigBuilder to add different sources to config

pub fn default_with(file_path: &str, env_prefix: &str) -> Result<Self>

where ConfigExt: Debug + DeserializeOwned,

Load file by given path and add environment variables with given prefix in addition to default config

Environment variables have highet priority then file and then default configuration

pub fn load_from<'a, S>(sources: S) -> Result<Self>

where ConfigExt: Debug + DeserializeOwned, S: IntoIterator<Item = ConfigSource<'a>>,

Load configuration from provided container with ConfigSource which override default config.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<ConfigExt: Debug> Debug for AppConfig<ConfigExt>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl<'de, ConfigExt> Deserialize<'de> for AppConfig<ConfigExt>

where ConfigExt: Debug + DeserializeOwned,

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,
