Struct Pdf 

pub struct Pdf {
    pub metadata: Option<Metadata>,
    pub pages: Vec<Page>,
    pub outline: Option<Outline>,
    pub attachments: Vec<Attachment>,
    pub page_labels: Vec<PageLabel>,
    pub viewer: Option<Viewer>,
    pub options: WriteOptions,
}

A document under construction. The fields are the composition: singleton slots are Options, pages keep the order given.

Fields

metadata: Option<Metadata>

Document information, if any.

pages: Vec<Page>

Pages, in reading order.

outline: Option<Outline>

Bookmark panel, if any.

attachments: Vec<Attachment>

Document-level attachments. Reordered by name, lexicographically by bytes, at emission — the name-tree keys must be sorted, so the order given here is not preserved. Duplicate names are an error.

page_labels: Vec<PageLabel>

Page-numbering ranges shown in viewer UI as /PageLabels. Reordered by first_page at emission. Must include a range starting at page 0 when non-empty; duplicate first_page values are an error.

viewer: Option<Viewer>

Viewer preferences, if any.

options: WriteOptions

File-emission options.

Implementations

impl Pdf

pub fn to_bytes(self) -> Result<Vec<u8>>

Serializes the document to complete PDF file bytes.

Fonts are shared document-wide: each distinct Standard14 face gets one font object, in first-use order. Images are embedded per page with no cross-page deduplication — the same raster drawn on two pages is stored twice. Groups follow the same rule: a canvas registered with Canvas::group on two different pages produces two Form XObjects — cross-page group sharing is deferred.

pub fn write_into(self, out: impl Write) -> Result<()>

Pdf::to_bytes streaming into a std::io::Write: the same bytes, delivered in bounded chunks instead of one buffer. Unlike to_bytes, an error can leave a prefix of the file already written to out. No flush is performed.

pub async fn write_into_with<S: AsyncByteSink>(self, sink: S) -> Result<S>

Pdf::to_bytes streaming into any AsyncByteSink — the asynchronous twin of Pdf::write_into. An error can leave a prefix of the file already written. Hands the sink back unflushed.

pub fn save(self, path: impl AsRef<Path>) -> Result<()>

Serializes and writes the document to path.

Trait Implementations

impl Debug for Pdf

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Pdf

fn default() -> Pdf

Returns the “default value” for a type.
