Struct Config

pub struct Config {
    pub server: ServerConfig,
    pub cache: CacheConfig,
}

Configuration structure for the server

Fields

server: ServerConfig

cache: CacheConfig

Implementations

impl Config

pub fn from_file(path: &str) -> Result<Self>

Load configuration from a TOML file

Errors

Returns an error if the file cannot be read or parsed.

pub fn with_env(self) -> Result<Self>

Create a new configuration, with it’s values updated from environment variables

This function reads environment variables prefixed with RANDOM_IMAGE_SERVER_ and updates the configuration accordingly. It supports the following variables:

• RANDOM_IMAGE_SERVER_PORT: The port for the server
• RANDOM_IMAGE_SERVER_HOST: The host for the server
• RANDOM_IMAGE_SERVER_LOG_LEVEL: The log level for the server
• RANDOM_IMAGE_SERVER_SOURCES: A comma-separated list of image sources (URLs or paths)
• RANDOM_IMAGE_SERVER_CACHE_BACKEND: The cache backend type, either in_memory or file_system

Errors

Returns an error if any environment variable is invalid or cannot be parsed.

pub fn with_env_backend(self, env: &impl EnvBackend) -> Result<Self>

Create a new configuration, with it’s values updated from environment variables.

Same as with_env, but allows passing a custom environment backend (e.g., for testing).

Errors

Returns an error if any environment variable is invalid or cannot be parsed.

pub fn socket_addr(&self) -> Result<SocketAddr, AddrParseError>

Get the socket address for the server

Errors

Shouldn’t fail unless the host or port is invalid.

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.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Config

fn eq(&self, other: &Config) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
