Represents the sets of limits an adapter/device supports.
Limits “better” than the default must be supported by the adapter and requested when requesting a device. If limits “better” than the adapter supports are requested, requesting a device will panic. Once a device is requested, you may only use resources up to the limits requested even if the adapter supports “better” limits.
Requesting limits that are “better” than you need may cause performance to decrease because the implementation needs to support more than is needed. You should ideally only request exactly what you need.

Fields
max_texture_dimension_1d: u32
Maximum allowed value for the size.width
of a texture created with TextureDimension::D1
.
Defaults to 8192. Higher is “better”.
max_texture_dimension_2d: u32
Maximum allowed value for the size.width
and size.height
of a texture created with TextureDimension::D2
.
Defaults to 8192. Higher is “better”.
max_texture_dimension_3d: u32
Maximum allowed value for the size.width
, size.height
, and size.depth_or_array_layers
of a texture created with TextureDimension::D3
.
Defaults to 2048. Higher is “better”.
max_texture_array_layers: u32
Maximum allowed value for the size.depth_or_array_layers
of a texture created with
TextureDimension::D1
or TextureDimension::D2
.
Defaults to 2048. Higher is “better”.
max_bind_groups: u32
Amount of bind groups that can be attached to a pipeline at the same time. Defaults to 4. Higher is “better”.
max_dynamic_uniform_buffers_per_pipeline_layout: u32
Amount of uniform buffer bindings that can be dynamic in a single pipeline. Defaults to 8. Higher is “better”.
max_dynamic_storage_buffers_per_pipeline_layout: u32
Amount of storage buffer bindings that can be dynamic in a single pipeline. Defaults to 4. Higher is “better”.
max_sampled_textures_per_shader_stage: u32
Amount of sampled textures visible in a single shader stage. Defaults to 16. Higher is “better”.
max_samplers_per_shader_stage: u32
Amount of samplers visible in a single shader stage. Defaults to 16. Higher is “better”.
max_storage_buffers_per_shader_stage: u32
Amount of storage buffers visible in a single shader stage. Defaults to 4. Higher is “better”.
max_storage_textures_per_shader_stage: u32
Amount of storage textures visible in a single shader stage. Defaults to 4. Higher is “better”.
max_uniform_buffers_per_shader_stage: u32
Amount of uniform buffers visible in a single shader stage. Defaults to 12. Higher is “better”.
max_uniform_buffer_binding_size: u32
Maximum size in bytes of a binding to a uniform buffer. Defaults to 16384. Higher is “better”.
max_storage_buffer_binding_size: u32
Maximum size in bytes of a binding to a storage buffer. Defaults to 128 MB. Higher is “better”.
max_vertex_buffers: u32
Maximum length of VertexState::buffers
when creating a RenderPipeline
.
Defaults to 8. Higher is “better”.
max_vertex_attributes: u32
Maximum length of VertexBufferLayout::attributes
, summed over all VertexState::buffers
,
when creating a RenderPipeline
.
Defaults to 16. Higher is “better”.
max_vertex_buffer_array_stride: u32
Maximum value for VertexBufferLayout::array_stride
when creating a RenderPipeline
.
Defaults to 2048. Higher is “better”.
max_push_constant_size: u32
Amount of storage available for push constants in bytes. Defaults to 0. Higher is “better”.
Requesting more than 0 during device creation requires Features::PUSH_CONSTANTS
to be enabled.
Expect the size to be:
- Vulkan: 128-256 bytes
- DX12: 256 bytes
- Metal: 4096 bytes
- DX11 & OpenGL don’t natively support push constants, and are emulated with uniforms, so this number is less useful but likely 256.
