Enum StoredDtype 

pub enum StoredDtype {
    Bf16,
    F32,
    Q8,
    Q4,
}

How a tensor’s elements are stored in the container.

Narrow on purpose, and unknown values are refused. The high-precision variants exist because the quant recipe protects norms, codebooks, and the speaker path — an artifact that claims a dtype we have never conformed is a refusal, not a best-effort read.

Variants

Bf16

bfloat16, kept verbatim from the checkpoint.

F32

32-bit float.

Q8

int8 with separate per-group scales.

Q4

int4, two elements per byte, with separate per-group scales.

Implementations

impl StoredDtype

pub const fn as_str(self) -> &'static str

The stable wire string.

pub fn parse(text: &str) -> Option<Self>

Parses a wire string, refusing anything unrecognized.

pub const fn storage_bytes(self, elements: u64) -> Option<u64>

Storage bytes for elements values, or None on overflow.

Q4 packs two elements per byte and rounds up, so an odd element count still occupies a whole trailing byte.
