## Member Data Documentation

## ◆ index_buffer

BufferView impeller::VertexBuffer::index_buffer

The index buffer binding used by the vertex shader stage.

Definition at line 18 of file vertex_buffer.h.

## ◆ index_type

IndexType impeller::VertexBuffer::index_type = IndexType::kUnknown

The type of indices in the index buffer. The indices must be tightly packed in the index buffer.

## ◆ vertex_count

size_t impeller::VertexBuffer::vertex_count = 0u

The total count of vertices, either in the vertex_buffer if the index_type is IndexType::kNone or in the index_buffer otherwise.
