Trait masonry::text2::TextStorage

pub trait TextStorage: 'static {
    // Required methods
    fn as_str(&self) -> &str;
    fn maybe_eq(&self, other: &Self) -> bool;

    // Provided methods
    fn add_attributes<'b>(
        &self,
        builder: RangedBuilder<'b, TextBrush, &'b str>
    ) -> RangedBuilder<'b, TextBrush, &'b str> { ... }
    fn links(&self) -> &[Link] { ... }
}

Text which can be displayed.

Required Methods

fn as_str(&self) -> &str

fn maybe_eq(&self, other: &Self) -> bool

Determines quickly whether two text objects have the same content.

To allow for faster checks, this method is allowed to return false negatives.

Provided Methods

fn add_attributes<'b>( &self, builder: RangedBuilder<'b, TextBrush, &'b str> ) -> RangedBuilder<'b, TextBrush, &'b str>

If this TextStorage object manages style spans, it should implement this method and update the provided builder with its spans, as required.

This takes &self, as we needed to call Self::as_str to get the value stored in the RangedBuilder

fn links(&self) -> &[Link]

Any additional Link attributes on this text.

If this TextStorage object manages link attributes, it should implement this method and return any attached Links.

Unlike other attributes, links are managed in Masonry, not in piet; as such they require a separate API.

Object Safety

This trait is not object safe.
