Struct PaginationContext 

pub struct PaginationContext {
    pub byte_offset: usize,
    pub event_index: usize,
    pub element_stack: Vec<String>,
    pub text_accumulator: String,
    pub page_number: usize,
}

Stateful pagination context for resumable page layout.

Tracks parsing/layout state so page N+1 can continue from where page N left off without re-parsing from the start.

Fields

byte_offset: usize

Current byte offset in the source document.

event_index: usize

Current event/token index.

element_stack: Vec<String>

Current element stack (path from root to current element).

text_accumulator: String

Accumulated text since last page break.

page_number: usize

Current page number.
