Struct vulkano::buffer::BufferUsage

pub struct BufferUsage {
    pub transfer_source: bool,
    pub transfer_destination: bool,
    pub uniform_texel_buffer: bool,
    pub storage_texel_buffer: bool,
    pub uniform_buffer: bool,
    pub storage_buffer: bool,
    pub index_buffer: bool,
    pub vertex_buffer: bool,
    pub indirect_buffer: bool,
}

Describes how a buffer is going to be used. This is not just an optimization.

If you try to use a buffer in a way that you didn’t declare, a panic will happen.

Some methods are provided to build BufferUsage structs for some common situations. However there is no restriction in the combination of BufferUsages that can be enabled.

Fields

transfer_source: bool

transfer_destination: bool

uniform_texel_buffer: bool

storage_texel_buffer: bool

uniform_buffer: bool

storage_buffer: bool

Implementations

impl BufferUsage

pub fn none() -> BufferUsage

Builds a BufferUsage with all values set to false.

pub fn all() -> BufferUsage

Builds a BufferUsage with all values set to true. Can be used for quick prototyping.

pub fn transfer_source() -> BufferUsage

Builds a BufferUsage with transfer_source set to true and the rest to false.

pub fn transfer_destination() -> BufferUsage

Builds a BufferUsage with transfer_destination set to true and the rest to false.

pub fn vertex_buffer() -> BufferUsage

Builds a BufferUsage with vertex_buffer set to true and the rest to false.

pub fn vertex_buffer_transfer_destination() -> BufferUsage

Builds a BufferUsage with vertex_buffer and transfer_destination set to true and the rest to false.

pub fn index_buffer() -> BufferUsage

Builds a BufferUsage with index_buffer set to true and the rest to false.

pub fn index_buffer_transfer_destination() -> BufferUsage

Builds a BufferUsage with index_buffer and transfer_destination set to true and the rest to false.
