Struct norad::Layer

pub struct Layer {
    pub glyphs: BTreeMap<GlyphName, Arc<Glyph>>,
}

A layer, corresponding to a 'glyphs' directory. Conceptually, a layer is just a collection of glyphs.

Fields

glyphs: BTreeMap<GlyphName, Arc<Glyph>>

Methods

impl Layer

pub fn load<P: AsRef<Path>>(path: P) -> Result<Layer, Error>

pub fn get_glyph<K: ?Sized>(&self, glyph: &K) -> Option<&Arc<Glyph>> where
    GlyphName: Borrow<K>,
    K: Ord, 

Returns a reference the glyph with the given name, if it exists.

pub fn get_glyph_mut<K: ?Sized>(&mut self, glyph: &K) -> Option<&mut Arc<Glyph>> where
    GlyphName: Borrow<K>,
    K: Ord, 

Returns a mutable reference to the glyph with the given name, if it exists.

pub fn contains_glyph(&self, name: &str) -> bool

Returns true if this layer contains a glyph with this name.

pub fn set_glyph<P: Into<PathBuf>>(&mut self, path: P, glyph: Glyph)

Set the given glyph. The name is taken from the glyph's name field. This replaces any existing glyph with this name.

pub fn delete_glyph(&mut self, name: &str)

Remove the named glyph from this layer.

pub fn iter_contents<'a>(&'a self) -> impl Iterator<Item = Arc<Glyph>> + 'a

Iterate over the glyphs in this layer.

Trait Implementations

impl Debug for Layer

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