Struct BufferDocument 

pub struct BufferDocument<'a> { /* private fields */ }

Compact, cache-friendly XML document representation.

Built on a flat array of 16-byte Node structs with power-of-2 page addressing. All string data lives in the arena or in the StringStore; qualified names are deduplicated via QNameTable.

Implementations

impl<'a> BufferDocument<'a>

pub fn kind(&self) -> DocumentKind

Returns the document kind (full or fragment).

pub fn options(&self) -> &BufferDocumentOptions

Returns the construction options.

pub fn root(&self) -> u32

Returns the root node index.

pub fn schema_set(&self) -> Option<&'a SchemaSet>

Returns the associated schema set, if any.

pub fn names(&self) -> &'a NameTable

Returns the shared name table.

pub fn first_child_of(&self, parent: u32) -> u32

Returns the first child of parent (always parent + 1).

This relies on the document-order layout: the first child node is stored immediately after its parent.

pub fn first_content_child_of(&self, parent: u32) -> Option<u32>

Returns the first content (non-attribute) child of parent, or None if the element has no children.

Attribute pairs precede content children in document order. This method skips over them by walking the next_sibling chain of attribute nodes until a non-attribute child is found.

pub fn subtree_end(&self, elem: u32) -> u32

Returns the flat index one past the last node in the subtree rooted at elem.

Walks ancestors until a node with a next_sibling is found and returns that sibling. If the root is reached without finding a sibling, returns self.nodes.len() (end of document).

pub fn get_element_by_id(&self, id: &str) -> Option<u32>

Looks up an element node by its xml:id value.

pub fn create_navigator(&self) -> BufferDocNavigator<'_>

Creates a navigator positioned at the document root.

pub fn create_navigator_at(&self, node_ref: u32) -> BufferDocNavigator<'_>

Creates a navigator positioned at the given node reference.

pub fn from_reader<R: BufRead>( reader: R, arena: &'a Bump, names: &'a NameTable, options: BufferDocumentOptions, schema_set: Option<&'a SchemaSet>, ) -> Result<Self, BufferDocumentError>

Parses an XML document from a reader into a BufferDocument.

pub fn from_reader_default<R: BufRead>( reader: R, arena: &'a Bump, names: &'a NameTable, ) -> Result<Self, BufferDocumentError>

Parses an XML document from a reader with default options.
