Struct Buffer 

pub struct Buffer {
    pub handle: u32,
}

A GPU buffer (VBO or EBO).

Created by GfxContext::create_buffer. Must be deleted with GfxContext::delete_buffer when done.

Fields

handle: u32

Implementations

impl Buffer

pub fn upload_bytes(&self, ctx: &GfxContext, data: &[u8], dynamic: bool)

Upload bytes to this buffer. dynamic: hint that the buffer will be updated frequently.

pub unsafe fn upload<T>(&self, ctx: &GfxContext, data: &[T], dynamic: bool)

Upload typed data to this buffer. T must be a plain-old-data type (the bytes are used as-is, in the layout T has in memory).

Safety

The byte representation of T must be well-defined (no padding traps, no floats encoding NaN, etc.). Use #[repr(C)] structs or primitive types.

pub fn subdata_bytes(&self, ctx: &GfxContext, offset: u32, data: &[u8])

Overwrite a sub-range of this buffer starting at offset bytes.

Trait Implementations

impl Clone for Buffer

fn clone(&self) -> Buffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Buffer

impl Debug for Buffer

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

Formats the value using the given formatter.

impl Eq for Buffer

impl PartialEq for Buffer

fn eq(&self, other: &Buffer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
