Struct Precision 

pub struct Precision(/* private fields */);

A numeric precision, validated at config load.

Kept as a newtype over the name rather than an enum because the set is open by design: any fNeXmY minifloat is legal, and the model crate maps the name to compile flags. What a type buys here is that a typo fails when the config is read, naming the file, instead of surfacing as a puzzling compile flag on node three — and that Self::bits lives with the thing it describes.

Serialized as the plain string, so existing configs are unchanged.

Implementations

impl Precision

pub fn as_str(&self) -> &str

pub fn bits(&self) -> Option<f64>

Bits per weight, for scaling a cost model between precisions.

Understands the fNeXmY family as well as the named shorthands, so a precision ladder can step onto f6e3m2 and have it actually cost something — the previous lookup table silently ignored anything it did not list by name.
