    wasm: &'a [u8],
    section_name: &str,
) -> Result<Option<&'a [u8]>, BinaryReaderError>
Expand description

Extract data of a custom section by name from raw WASM bytes.

Returns Ok(Some(data)) if the section is found, Ok(None) if the WASM is valid but the section is not present, and Err if the WASM is malformed. The error preserves the underlying parser diagnostic.
