Struct TextLineIter 

pub struct TextLineIter<'a> { /* private fields */ }

𝐓 🧱 🔄 Iterates fixed-width inline layout steps over a symbol stream.

^{📍 text/layout::TextLineIter}

^{📦 size_of::<TextLineIter>() == 24 bytes / 192 bits #️⃣ #[cfg(target_pointer_width = “32”)]}

^{📦 size_of::<TextLineIter>() == 40 bytes / 320 bits #️⃣ #[cfg(target_pointer_width = “64”)]}

---

TextLineIter repeatedly applies TextLayout::step with the same inline width, advancing through the returned carry cursor.

This is mechanical line stepping. It does not perform semantic prose wrapping, whitespace trimming, paragraph handling, indentation, or hard-break handling.

Implementations

impl<'a> TextLineIter<'a>

pub const fn new( layout: &'a TextLayout, symbols: &'a [TextSymbol], width: TextUnit, ) -> Self

Creates a line iterator starting at the beginning of symbols.

pub const fn from_cursor( layout: &'a TextLayout, symbols: &'a [TextSymbol], cursor: TextCursor, width: TextUnit, ) -> Self

Creates a line iterator starting at cursor.

pub const fn cursor(&self) -> TextCursor

Returns the current continuation cursor.

pub const fn width(&self) -> TextUnit

Returns the fixed inline width used by this iterator.

pub const fn is_done(&self) -> bool

Returns whether this iterator has terminated and can produce no further steps.

pub const fn next( &mut self, out_spans: &mut [TextLayoutSpan], ) -> Option<TextLayoutStep>

Computes the next fixed-width layout step.

Writes the produced spans into out_spans and returns the step outcome.

The valid output span prefix is &out_spans[..step.span_count].
