Struct Mesh

pub struct Mesh { /* private fields */ }

A mesh whose vertices may be populated by a list of render primitives.

This is a convenience type for simplifying backend implementations.

Implementations

impl Mesh

pub fn new() -> Self

Construct a new empty Mesh with default glyph cache dimensions.

pub fn with_glyph_cache_dimensions(glyph_cache_dims: [u32; 2]) -> Self

Construct a Mesh with the given glyph cache dimensions.

pub fn fill<P, I>( &mut self, viewport: Rect, dpi_factor: f64, image_map: &Map<I>, primitives: P, ) -> Result<Fill, CacheWriteErr>

where P: PrimitiveWalker, I: ImageDimensions,

Fill the inner vertex buffer from the given primitives.

• viewport: the window in which the UI is drawn. The width and height should be the physical size (pixels).
• dpi_factor: the factor for converting from conrod’s DPI agnostic point space to the pixel space of the viewport.
• image_map: a map from image IDs to images.
• primitives: the sequence of UI primitives in order of depth to be rendered.

pub fn glyph_cache(&self) -> &GlyphCache<'_>

The rusttype glyph cache used for managing caching of glyphs into the pixel buffer.

pub fn glyph_cache_pixel_buffer(&self) -> &[u8]

The CPU-side of the glyph cache, storing all necessary pixel data in a single slice.

pub fn commands(&self) -> Commands<'_>

Produce an Iterator yielding Commands.

These commands describe the order in which unique draw commands and scizzor updates should occur.

pub fn vertices(&self) -> &[Vertex]

The slice containing all vertices produced by the fill function.

Note that these vertices may be represent geometry across multiple Commands.

Trait Implementations

impl Debug for Mesh

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

Formats the value using the given formatter.
