Struct enso_flexer::prelude::reader::BookmarkManager [−][src]
pub struct BookmarkManager { pub matched_bookmark: BookmarkId, pub rule_bookmark: BookmarkId, // some fields omitted }
Expand description
Contains and manages bookmarks for a running lexer.
Some of its operations operate on a specific Reader
. It is undefined behaviour to not pass
the same reader to all calls for a given bookmark manager.
Fields
matched_bookmark: BookmarkId
Expand description
The bookmark used by the flexer to mark the end of the last matched segment of the input.
rule_bookmark: BookmarkId
Expand description
A bookmark used by the flexer to deal with overlapping rules that may fail later.
