Struct PositionedItems

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

Writer for a positioned items array.

This struct is created by ShowPositioned::items.

Implementations

impl<'a> PositionedItems<'a>

pub fn show(&mut self, text: Str<'_>) -> &mut Self

Show a continuous string without adjustments.

The encoding of the text depends on the font.

pub fn adjust(&mut self, amount: f32) -> &mut Self

Specify an adjustment between two glyphs.

The amount is specified in thousands of units of text space and is subtracted from the current writing-mode dependent coordinate.

Methods from Deref<Target = Array<'a>>

pub fn len(&self) -> i32

The number of written items.

pub fn is_empty(&self) -> bool

Whether no items have been written so far.

pub fn push(&mut self) -> Obj<'_>

Start writing an arbitrary item.

pub fn item<T: Primitive>(&mut self, value: T) -> &mut Self

Write an item with a primitive value.

This is a shorthand for array.push().primitive(value).

pub fn items<T: Primitive>( &mut self, values: impl IntoIterator<Item = T>, ) -> &mut Self

Write a sequence of items with primitive values.

Trait Implementations

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a> DerefMut for PositionedItems<'a>

fn deref_mut(&mut self) -> &mut Self::Target
