Struct Config 

pub struct Config {
    pub listen: String,
    pub storage_dir: Option<PathBuf>,
}

Server configuration, sourced from the process environment.

Fields

listen: String

host:port the HTTP server binds to (FERRO_OCI_LISTEN).

storage_dir: Option<PathBuf>

Optional filesystem directory for blob bytes (FERRO_OCI_STORAGE_DIR). When None, an in-memory blob store is used — convenient for smoke tests and conformance runs, but non-durable.

Implementations

impl Config

pub fn from_env() -> Self

Read the configuration from the process environment, applying defaults for anything unset.

pub fn from_raw(listen: Option<String>, storage_dir: Option<PathBuf>) -> Self

Build a Config from already-resolved listen / storage-dir values, applying defaults for None.

Factored out of from_env so the parsing and default rules are unit-testable without mutating the process environment (which unsafe_code = forbid disallows here). An empty storage_dir path is normalised to “in-memory”.

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

Parse and validate the listen address.

Errors

Returns an error string when listen is not a valid host:port socket address.

pub fn blob_store(&self) -> Result<SharedBlobStore, Box<dyn Error>>

Build the SharedBlobStore this config describes.

Errors

Returns an error when a filesystem store is requested but its directory cannot be created or opened.

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 Eq for Config

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.
