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_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_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.
