Errors

There is no ops::codec module. The crate’s shared parser/serializer error type is AdapterError, which lives in molex::ops::error and is re-exported at the crate root as molex::AdapterError (source: src/ops/error.rs).

The assembly binary wire format lives in molex::ops::wire; the structural-transform routines (Kabsch alignment, RMSD) live in molex::ops::transform.

Error type

AdapterError is the Err variant for the Assembly parse entry points (from_pdb / from_mmcif / from_bcif / from_file and the *_to_all_models multi-model functions), the PDB writers, and the assembly wire codec.

pub enum AdapterError {
    /// The input bytes/text do not conform to the expected format.
    InvalidFormat(String),
    /// A PDB file could not be parsed.
    PdbParseError(String),
    /// An error occurred during binary serialization or deserialization.
    SerializationError(String),
}

Density and trajectory adapters use their own error types (DensityError from the MRC adapter, for instance); only the structure-and-wire paths funnel through AdapterError.
