Struct DumpLatches 

pub struct DumpLatches { /* private fields */ }

One-shot diagnostic latches for one model.

The named fields are the latches with a caller that already holds the struct; keyed covers the long tail of ATLAS_*_DUMP gates, which are numerous, scattered, and identical in shape — a field each would be noise, and a static each is the bug.

Implementations

impl DumpLatches

pub fn keyed(&self, key: &'static str) -> bool

true exactly once per model for key. Use for the ATLAS_*_DUMP gates that would otherwise each grow a static AtomicBool.

Call it only when the dump is actually wanted — it consumes the shot, so gating on the env var FIRST keeps a disabled dump from burning it.

Trait Implementations

impl Debug for DumpLatches

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

Formats the value using the given formatter.

impl Default for DumpLatches

fn default() -> DumpLatches

Returns the “default value” for a type.
