Enum Source

pub enum Source {
    ClientOverride,
    File,
    Env,
    Runtime,
    TestOverride,
}

Configuration source layers in priority order.

Resolution order is always: TestOverride -> Runtime -> Env -> File -> ClientOverride -> Default.

Smaller priority() number = higher precedence.

Variants

ClientOverride

Values set by the config snapshot sent from the client during proc bootstrap.

File

Values loaded from configuration files (e.g., YAML).

Env

Values read from environment variables at process startup. Higher priority than File and ClientOverride, but lower than Runtime/TestOverride.

Runtime

Values set programmatically at runtime. Highest stable priority layer; only overridden by TestOverride.

TestOverride

Ephemeral values inserted by tests via ConfigLock::override_key. Always wins over all other sources; removed when the guard drops.

Trait Implementations

impl Clone for Source

fn clone(&self) -> Source

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Source

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Source

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Source

fn eq(&self, other: &Source) -> 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.
