donner::xml::SourceAnchorSpan

struct donner::xml::SourceAnchorSpan

Pair of anchors representing a source span.

Class Members
SourceAnchorId	end	End anchor.
SourceAnchorId	start	Start anchor.

donner::xml::XMLSourceStore::ResourceLimits

struct donner::xml::XMLSourceStore::ResourceLimits

Resource limits for retained anchors and anchor-update work.

Class Members
size_t	maximumAnchorUpdateWorkPerEdit = 1024 * 1024	Maximum live anchors visited by one source edit.
size_t	maximumLiveAnchorCount = 1024 * 1024	Maximum simultaneously live source anchors.
size_t	maximumSourceSize = 16 * 1024 * 1024	Maximum source bytes retained after an edit.

donner::xml::XMLSourceStore::ResourceStats
