Enum LineSignal 

pub enum LineSignal {
    Enter {
        split_at: usize,
    },
    SoftNewline {
        split_at: usize,
    },
    BackspaceAtStart,
    ArrowUp,
    ArrowDown,
    SelectBlockUp {
        caret: usize,
    },
    SelectBlockDown {
        caret: usize,
    },
    LinkOpen {
        open_at: usize,
    },
}

Emitted when a key would carry the edit out of the line itself; the parent (a BlockEditor) drains these via RichTextLine::take_signal.

Variants

Enter

Parent splits the line at split_at, drops the suffix into a new block, and re-focuses.

Fields

split_at: usize

SoftNewline

Same as Enter, but the new block is flagged a soft-break continuation (no top spacing, reads as one paragraph).

Fields

split_at: usize

BackspaceAtStart

Caret was at byte 0 with no selection; parent decides whether to merge with the previous block, delete an empty block, or no-op.

ArrowUp

ArrowDown

SelectBlockUp

Ctrl+Shift+Up: parent extends the selection up across the block boundary from caret, instead of moving focus.

Fields

caret: usize

SelectBlockDown

Mirror of SelectBlockUp extending down.

Fields

caret: usize

LinkOpen

User typed [[; parent opens a LinkPopover anchored at open_at. Brackets fall through to the inner input — the popover’s commit-link logic strips them.

Fields

open_at: usize

Trait Implementations

impl Clone for LineSignal

fn clone(&self) -> LineSignal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineSignal

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

Formats the value using the given formatter.

impl PartialEq for LineSignal

fn eq(&self, other: &LineSignal) -> 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.
