Crate escriba_core 

escriba-core — foundational types.

No I/O. No rendering. No tatara-lisp. Just the typed vocabulary every other escriba crate speaks:

• Position — line + column, 0-indexed, UTF-8 char offsets.
• Range — half-open [start, end).
• Cursor — anchor + head (for selection growth).
• Selection — multi-cursor ordered set.
• Mode — the vim-ish modal state.
• Motion / Operator — compose into commands.
• Edit — primitive mutation.
• Action — top-level dispatched-to-buffer command.
• BufferId / WindowId — opaque identifiers.

Every type derives schemars::JsonSchema so escriba-api can emit an OpenAPI spec over the full domain surface — the editor’s entire public shape is spec-first by construction.

Modules

action

damage

Damage + LineDelta — the typed dirty-region boundary.

edit

gen

EditGen — the monotonic edit-generation stamp.

id

Opaque identifiers — one counter per domain. All are transparent newtypes so serde emits them as plain numbers.

jumplist

The jumplist — where you were before the editor moved you a long way.

mode

motion

position

range

selection

Structs

Anchored

A value computed against a specific edit generation.

Bytes

UTF-8 bytes — what &str indexing and the regex crate speak.

Chars

Unicode scalar values — what escriba’s own Position and match offsets use.

Offset

An offset counted in a specific Scale.

Ruler

Converts between scales for one specific text.

Utf16Units

UTF-16 code units — what LSP specifies, and nothing else.

Enums

Bound

Does a search from an anchor consider the anchor itself?

Traits

Scale

A unit an offset can be counted in.
