Struct Region 

#[non_exhaustive]
pub struct Region {
    pub open_fence: Span,
    pub content: Span,
    pub close_fence: Span,
    pub body: Span,
    pub body_before: Span,
    pub body_after: Span,
}

A located embed region in host-file byte coordinates (the content is not parsed).

body_before and body_after are the host text on either side of the block. With the three region spans they tile the source exactly:

body_before ++ open_fence ++ content ++ close_fence ++ body_after == source

Every byte is in exactly one span (a leading UTF-8 BOM heads body_before), so a caller can rebuild the host without losing one.

body is the historical one-sided view of the same thing: the suffix after the close fence for frontmatter, the prefix before the open fence for endmatter. For a mid-document block (an HTML <script> data island) that is only ever half the host — prefer the two sides when reassembling.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

open_fence: Span

content: Span
