Struct Config 

pub struct Config {
    pub llm: Vec<LlmConfig>,
}

The whole configuration tree, rooted at the file.

llm is an array of tables ([[llm]]), not a single [llm] section, and it is that shape from the day drep init first wrote one - a phase before failover could read it, precisely so the file format would not have to change underneath a file drep itself wrote. The list is a preference order: Self::providers is the failover chain.

#[serde(default)] means a file with an empty body deserializes successfully; [validate] is what then rejects it, because a config declaring no provider cannot run the mandatory LLM layer.

Fields

llm: Vec<LlmConfig>

Implementations

impl Config

pub fn providers(&self) -> Vec<&LlmConfig>

The failover chain: every enabled provider, in file order.

The single definition of “which providers are in play”. enabled is an opt-out, so a disabled entry is skipped wherever it sits - a disabled head falls through to the entry below it rather than producing NotConfigured, which is what parking the local model was always meant to do.

A Vec rather than an iterator because every caller wants a length or an index (the chain numbers its providers in error messages) and the list is at most a handful of entries.

Trait Implementations

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

where Config: Default,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
