Implementations

impl Config

pub fn new() -> Self

Creates a new configuration instance from environment variables

Loads configuration from environment variables or .env file. Uses default values if environment variables are not found.

Returns

A new Config instance

pub fn with_rate_limit_type( rate_limit_type: RateLimitType, safety_margin: f64, ) -> Self

Creates a new configuration instance with a specific rate limit type

Arguments

• rate_limit_type - The type of rate limit to enforce
• safety_margin - A value between 0.0 and 1.0 representing the percentage of the actual limit to use

Returns

A new Config instance

pub async fn pg_pool(&self) -> Result<Pool<Postgres>, Error>

Creates a PostgreSQL connection pool using the database configuration

Returns

A Result containing either a PostgreSQL connection pool or an error
