Function gen_sum_code_v0 

Source 
pub fn gen_sum_code_v0(
    path: &Path,
    bits: u32,
    wide: bool,
    add_units: bool,
) -> IsccResult<SumCodeResult>
Expand description

Generate a composite ISCC-CODE from a file in a single pass.

Opens the file at path, reads it with an optimal buffer size, and feeds both DataHasher (CDC/MinHash) and InstanceHasher (BLAKE3) from the same read buffer. Composes the final ISCC-CODE from the Data-Code and Instance-Code internally. This avoids multiple passes over the file and eliminates per-chunk FFI overhead in language bindings.

When add_units is true, the result includes the individual Data-Code and Instance-Code ISCC strings at the requested bits precision.
