Why an apply failed: range or line index out of bounds, or invariants broken before normalization could repair them.

Variants

MarkOutOfRange

Fields

start: Usv

end: Usv

len: Usv

LineOutOfRange

Fields

line: usize

lines: usize

SplitPositionOutOfRange

Fields

at: Usv

len: Usv

SplitAtNewline

Fields

at: Usv

LineCountMismatch

Fields

lines: usize

segments: usize

DeltaBaseMismatch

The text delta’s expected base length disagreed with the content: it was built against a different revision.

Fields

expected: usize

actual: usize

IslandSlotInInsert

An Op::Insert carried a raw ISLAND_SLOT, which would leave a slot with no backing Island. Islands are created through IslandOp::Insert, never a text splice, so a whole-field splice carrying slots must be split into a slot-stripped delta plus one IslandOp::Insert per slot.

AnchorIdCollision

A MarkOp::Add of an anchor whose id is already live in the field. Rejected rather than replaced (which would retarget a live thread) or coexisting (which RemoveAnchor cannot disambiguate).

Fields

id: String

EmptyAnchorId

A MarkOp::Add of an anchor with the empty id.

UnknownIslandId

An IslandOp::Set naming an id no island in the field carries.

Fields

id: String

IslandIdCollision

An IslandOp::Insert whose id is already live in the field. Set addresses by id, so a duplicate is an island neither op can name.

Fields

id: String

EmptyIslandId

An IslandOp::Insert carrying the empty id.

IslandInsertOutOfRange

An IslandOp::Insert whose at is past the end of the text the delta and this bundle’s earlier island ops left.

Fields

at: Usv

len: Usv

BlockIslandNotAlone

An island op would leave a block-only island’s slot (IslandType::block_only, a table) sharing its line with other content. Markdown writes such an island by breaking the line around it, so the op that lands one mid-line is refused rather than restructuring the author’s blocks. at is the slot’s position.

Fields

at: Usv

NestingTooDeep

A LineOp::SetContainers nested a line deeper than MAX_NESTING_DEPTH.

Fields

line: usize

depth: usize

max: usize

BadHeadingLevel

A LineOp::SetKind naming a heading level outside 1..=6. Refused because normalize does not repair it: the level reaches export as that many #, which CommonMark reads back as a literal-hash paragraph.

Fields

line: usize

level: u8
