#![allow(rustdoc::private_intra_doc_links)]//! This is the place where everything editor-related is stored (data-wise) and displayed (ui-wise).//! The main point of interest in this crate is [`Editor`] type, which is used in every other Zed part as a user input element.//! It comes in different flavors: single line, multiline and a fixed height one.//!//! Editor contains of multiple large submodules://! * [`element`] — the place where all rendering happens//! * [`display_map`] - chunks up text in the editor into the logical blocks, establishes coordinates and mapping between each of them.//!   Contains all metadata related to text transformations (folds, fake inlay text insertions, soft wraps, tab markup, etc.).//! * [`inlay_hint_cache`] - is a storage of inlay hints out of LSP requests, responsible for querying LSP and updating `display_map`'s state accordingly.//!//! All other submodules and structs are mostly concerned with holding editor data about the way it displays current buffer region(s).//!//! If you're looking to improve Vim mode, you should check out Vim crate that wraps Editor and overrides its behavior.pub mod actions;mod blink_manager;mod clangd_ext;pub mod code_context_menus;pub mod
