Struct OpcPackage 

pub struct OpcPackage {
    pub content_types: ContentTypes,
    pub package_rels: Relationships,
    pub part_rels: HashMap<String, Relationships>,
    pub parts: HashMap<String, Vec<u8>>,
}

An in-memory representation of an OPC package (ZIP archive).

Fields

content_types: ContentTypes

Content types from [Content_Types].xml

package_rels: Relationships

Package-level relationships from _rels/.rels

part_rels: HashMap<String, Relationships>

Part-level relationships keyed by the part they belong to. Key is the part name (e.g. “/word/document.xml”), value is the parsed relationships.

parts: HashMap<String, Vec<u8>>

All parts keyed by their URI (e.g. “/word/document.xml”).

Implementations

impl OpcPackage

pub fn open<P: AsRef<Path>>(path: P) -> Result<Self, OpcError>

Open an OPC package from a file path.

pub fn from_reader<R: Read + Seek>(reader: R) -> Result<Self, OpcError>

Open an OPC package from any reader that implements Read + Seek.

pub fn save<P: AsRef<Path>>(&self, path: P) -> Result<(), OpcError>

Save the OPC package to a file path.

pub fn write_to<W: Write + Seek>(&self, writer: W) -> Result<(), OpcError>

Write the OPC package to any writer.

pub fn get_part(&self, part_name: &str) -> Option<&[u8]>

Get raw bytes of a part by its URI.

pub fn set_part(&mut self, part_name: &str, data: Vec<u8>)

Set (or replace) a part’s raw bytes.

pub fn get_part_rels(&self, part_name: &str) -> Option<&Relationships>

Get the relationships for a specific part.

pub fn get_or_create_part_rels(&mut self, part_name: &str) -> &mut Relationships

Get or create the relationships for a specific part.

pub fn resolve_rel_target(source_part: &str, rel_target: &str) -> String

Resolve the target URI of a relationship relative to its source part.

. and .. segments are collapsed, so a target such as ../media/image1.png on /word/charts/chart1.xml resolves to /media/image1.png and matches the key it is stored under. Without this, parts referenced through a parent directory could never be found.

pub fn main_document_part(&self) -> Option<String>

Find the main document part URI by looking at package relationships.

pub fn new() -> Self

Create an empty package with the universal OPC content types.

pub fn with_main_part(part_name: &str, content_type: &str) -> Self

Create a package whose office document relationship targets a main part.
