Struct PdfLoadLimits 

pub struct PdfLoadLimits { /* private fields */ }

Parser-internal limits applied while loading a PDF.

The default preserves the historical parser behavior (no caps). Callers that need stricter limits can set individual caps before loading.

Implementations

impl PdfLoadLimits

pub fn new() -> Self

Create a limit set with no caller overrides.

pub fn max_object_depth(self, depth: u32) -> Self

Set the maximum page-tree/object traversal depth.

pub fn max_image_pixels(self, pixels: u64) -> Self

Set the maximum decoded image pixel count.

pub fn max_stream_bytes(self, max_bytes: u64) -> Self

Set the maximum decoded stream size in bytes.

Values above ~4 GB are clamped to u32::MAX - 1 (≈ 4 GB − 1) due to internal storage as u32. For the intended use-case (decompression-bomb protection at 32 MB–1 GB), the 4 GB ceiling is more than sufficient.

Any call to [Stream::decoded] or [Stream::decoded_image] that produces more bytes than max_bytes returns Err(DecodeFailure::StreamTooLarge { observed, limit }).
