Struct OpenOptions 

pub struct OpenOptions {
    pub parsing_mode: ParsingMode,
    pub password: Option<String>,
    pub max_decompressed_stream_size: u64,
    pub max_compression_ratio: u32,
    pub max_operators_per_page: u64,
    pub max_endstream_scan_distance: u64,
}

Options for opening a PDF document.

All fields have sensible defaults via the Default implementation. Soft limits can be adjusted for trusted inputs that exceed the defaults.

Fields

parsing_mode: ParsingMode

Parsing mode (default: ParsingMode::Lenient).

password: Option<String>

Password for encrypted documents (default: None).

max_decompressed_stream_size: u64

Maximum decompressed stream size in bytes (default: 256 MB).

Prevents decompression bombs.

max_compression_ratio: u32

Maximum compression ratio before aborting (default: 1000:1).

A ratio exceeding this strongly indicates a zip bomb.

max_operators_per_page: u64

Maximum content stream operators per page (default: 10,000,000).

max_endstream_scan_distance: u64

Maximum distance to scan for endstream keyword (default: 16 MB).
