Errors

Generated with Grok Build: Grok 4.5 · xAI Imagine (/imagine)

Hand-rolled in src/error.rs — no thiserror / anyhow.

pub enum ParserError {
    Io { path, source },
    UnsupportedFormat { path, reason },
    MissingTensor { name, path },
    InvalidLayout { path, reason },
    ExpertOutOfRange { block, expert, available },
}
pub type Result<T> = std::result::Result<T, ParserError>;

Variant	When
Io	File read failure
UnsupportedFormat	Bad magic, wrong version, unknown value types, sanity limits
MissingTensor	Lookup / no projections for expert
InvalidLayout	EOF overrun, stride not divisible, rank errors
ExpertOutOfRange	Expert index ≥ stacked expert count

Implements Display + std::error::Error (source only for Io).
