Struct ValueTrace 

pub struct ValueTrace {
    pub final_value: TracedValue,
    pub history: Vec<TracedValue>,
}

Trace of a single configuration value.

Fields

final_value: TracedValue

The final value (from highest priority source)

history: Vec<TracedValue>

All values from all sources, in priority order (lowest first)

Implementations

impl ValueTrace

pub fn new(history: Vec<TracedValue>) -> Option<Self>

The last value in the history is considered the final value. The is_final flag is automatically set on the last value.

pub fn was_overridden(&self) -> bool

Check if this value was overridden (has more than one source).

pub fn source_count(&self) -> usize

Get the number of sources that provided this value.
