GPUI.Text.Buffer (gpui v0.2.0-rc.1)

Copy Markdown View Source

Persistent native Rope text storage with revisioned atomic edits.

This is a model primitive. It does not represent a file, editor, language, gutter, or workspace. Consumers own those policies and may later attach one or more renderer primitives to the same buffer.
