Struct EnvWarningSink 

pub struct EnvWarningSink { /* private fields */ }

Sink for env-precedence warnings.

One global instance (env_warning_sink) deduplicates warnings by the lifeloop key name so a process that resolves the same alias many times only emits one warning. Tests can inspect drain to assert precedence behavior.

Implementations

impl EnvWarningSink

pub fn drain(&self) -> Vec<EnvPrecedenceWarning>

Drain queued warnings (FIFO). Each warning is yielded at most once: a key that has already been drained will not appear again in a later call, even if its alias resolves repeatedly.

Trait Implementations

impl Debug for EnvWarningSink

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

Formats the value using the given formatter.

impl Default for EnvWarningSink

fn default() -> EnvWarningSink

Returns the “default value” for a type.
