Struct SpanSet 

pub struct SpanSet {
    pub spans: Vec<Span>,
}

An ordered cover of an input by lexical spans.

Fields

spans: Vec<Span>

Spans in ascending, non-overlapping order.

Implementations

impl SpanSet

pub fn total_len(&self) -> u64

Sum of all span lengths. Saturates rather than panicking on absurd input.

pub fn validate(&self, declared_len: u64) -> Result<()>

Require a contiguous cover of exactly [0, declared_len).

Returns crate::ErrorClass::CoverageViolation for a gap, overlap, wrong total, or length overflow, and crate::ErrorClass::InvalidPdfStructure for a degenerate zero-length span. This is the internal self-check that turns a scanner bug into a loud classified failure instead of silent byte loss.

pub fn span_at(&self, offset: u64) -> Option<Span>

The span containing offset, if any. Binary search over sorted starts.
