Struct Editor 

pub struct Editor {
    pub lines: Vec<String>,
    pub cursor_row: usize,
    pub cursor_col: usize,
    pub mode: VimMode,
    pub ex_buffer: String,
    pub esc_armed: bool,
    pub yank: Vec<String>,
    pub pending_op: Option<char>,
}

Fields

lines: Vec<String>

cursor_row: usize

cursor_col: usize

mode: VimMode

ex_buffer: String

esc_armed: bool

Tracks whether the previous keypress was Esc. Two Escs in a row from any mode cancel the surrounding modal — same shape SPEC §4 specifies for “close all modals.”

yank: Vec<String>

Single-register yank buffer for yy / dd → p. Only holds full lines; word-level yanks aren’t in PR-UI-7 scope. Empty Vec means “nothing to paste.”

pending_op: Option<char>

Tracks whether the previous Normal-mode key was d or y. dd deletes the line, yy yanks it. The pending-op state clears on any non-matching key so dx doesn’t leave the editor in a half-operation.

Implementations

impl Editor

pub fn body(&self) -> String

Final body for sending. Joins lines with \n; trailing blank lines are stripped so a single newline at the bottom doesn’t sneak past the operator’s intent.

pub fn is_empty(&self) -> bool

pub fn apply_key(&mut self, k: KeyEvent) -> EditorAction

Apply a keypress and return what the surrounding modal should do. Held under &mut self so tests can drive the editor deterministically without a Terminal.

Trait Implementations

impl Clone for Editor

fn clone(&self) -> Editor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Editor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Editor

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Editor

fn eq(&self, other: &Editor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
