    """<p>Returns a structured, line-level diff between two blob versions in a repository. The diff is returned as an ordered list of hunks, where each hunk represents a contiguous run of changed lines together with any surrounding unchanged context lines.</p> <p>Results are paginated. Use <code>MaxResults</code> and <code>NextToken</code> to retrieve additional pages.</p> <p>For the typical usage workflow, see <a>GetDifferences</a>.</p>

    Args:
        repository_name: <p>The name of the repository that contains the blobs to compare.</p>
        after_blob_id: <p>The ID of the "after" (destination) blob in the diff. Typically the value of <code>afterBlob.blobId</code> from a <code>Difference</code> object returned by <a>GetDifferences</a>.</p>
        before_blob_id: <p>The ID of the "before" (source) blob in the diff. Typically the value of <code>beforeBlob.blobId</code> from a <code>Difference</code> object returned by <a>GetDifferences</a>.</p> <p>If you do not specify a value, the operation returns a diff against an empty before-state. This is equivalent to treating the file as newly added.</p>
        context_lines: <p>The number of unchanged lines of context to include before and after each block of changes in a hunk. Valid values are 0 through 20. Defaults to <code>3</code>.</p>
        ignore_whitespace: <p>Specifies whether to ignore whitespace-only changes when computing the diff. When <code>true</code>, the operation treats lines that differ only in whitespace as unchanged. Defaults to <code>false</code>.</p>
        max_results: <p>The maximum number of <code>DiffHunk</code> entries to return in a single response page. Defaults to <code>100</code>.</p>
        next_token: <p>An enumeration token that returns the next batch of results when present in a request.</p>

    Raises:
