storage: StorageConfig

Implementations

impl Config

pub fn from_yaml_str(text: &str) -> Result<Self, SignalError>

Parses a single, self-contained config from YAML text, interpolating ${VAR} placeholders and checking that every route names a configured provider. A file that uses extends needs to be loaded from where it lives, with Config::from_file or $SIGNAL_CONFIG, so its parents can be found.

pub fn from_layers( layers: impl IntoIterator<Item = (Option<String>, Layer)>, ) -> Result<Self, SignalError>

Merges a chain of layers, given lowest priority first, each with the name of the file it came from (for error messages):

• providers merge by name, and a later layer’s entry replaces an earlier one’s;
• a later layer’s routes go before the earlier layers’ routes, so the more specific file is matched first and the shared defaults still catch everything else;
• storage comes from the last layer that sets it.

Routes are checked against the merged providers.

pub fn load( sources: &[ConfigSource], opts: &LoadOptions, ) -> Result<Self, SignalError>

Loads and merges sources once, resolving secret placeholders; see crate::source.

pub fn from_file(path: &Path) -> Result<Self, SignalError>

pub fn discover() -> Result<Self, SignalError>

$SIGNAL_CONFIG if set (one or more comma-separated local files, which must then exist, or remote URLs), else ./signal.yaml if present, else the zero-config default. Remote files are fetched once, with the cache fallback described in crate::source.

pub fn routing(&self) -> RoutingConfig

pub fn provider_names(&self) -> Vec<&'static str>

Names of the providers this config makes available. console is always present because routing falls back to it.
