Struct Config 

pub struct Config {
    pub base_url: String,
    pub subscription_key: String,
    pub api_key: String,
    pub access_key: Option<String>,
    pub timeout: Duration,
}

Connection details and credentials for a single ALAT gateway.

A Config is consumed by Client::new. It is cheap to clone and holds no live connections.

Authentication

APIM gates every product with a subscription key (Ocp-Apim-Subscription-Key). On top of that, ALAT identifies the calling software channel with an API key (x-api-key). A subset of products (bills & airtime) additionally require an access key sent in an access header — supply it via Config::with_access_key when you use those endpoints.

Fields

base_url: String

Absolute base URL of the APIM gateway (where API calls go, not the sign-up portal), e.g. https://playground.azure-api.net. Stored without a trailing slash.

subscription_key: String

APIM subscription key, sent as the Ocp-Apim-Subscription-Key header. Obtained from your subscription on the ALAT developer portal.

api_key: String

Channel API key, sent as the x-api-key header. Identifies your registered application/partner to ALAT’s core systems.

access_key: Option<String>

Optional “access” credential required by the bills & airtime products, sent as the access header. None if you do not use those endpoints.

timeout: Duration

Maximum duration to wait for each request before failing with a Network timeout error.

Implementations

impl Config

pub fn new( base_url: impl Into<String>, subscription_key: impl Into<String>, api_key: impl Into<String>, ) -> Self

Creates a configuration pointing at an explicit gateway host.

This is the honest, production-oriented constructor: you name the gateway Wema issued to you. Trailing slashes are trimmed.

use alat::Config;
let config = Config::new("https://your-gateway.wemabank.com", "sub_key", "api_key");
assert_eq!(config.base_url, "https://your-gateway.wemabank.com");

pub fn playground( subscription_key: impl Into<String>, api_key: impl Into<String>, ) -> Self

Configuration for the Playground sandbox gateway (https://playground.azure-api.net; sign up at https://playground.alat.ng).

Use this for wallet creation, account maintenance, statements, bills, and airtime — the products published on that portal.

pub fn apim_dev( subscription_key: impl Into<String>, api_key: impl Into<String>, ) -> Self

Configuration for the APIM Dev sandbox (https://wema-alatdev-apimgt.azure-api.net).

Use this for the funds-transfer / name-enquiry product (/funds-transfer-open), which is published on that portal rather than on Playground.

pub fn with_access_key(self, access_key: impl Into<String>) -> Self

Attaches the access credential required by bills & airtime endpoints (builder style).

use alat::Config;
let config = Config::playground("sub", "api").with_access_key("bills_access_token");
assert!(config.access_key.is_some());

pub fn with_timeout(self, timeout: Duration) -> Self

Overrides the default per-request timeout (builder style).

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.
