Struct rerun::external::eframe::egui_wgpu::wgpu::ShaderRuntimeChecks

pub struct ShaderRuntimeChecks {
    pub bounds_checks: bool,
    pub force_loop_bounding: bool,
}

Describes how shader bound checks should be performed.

Fields

bounds_checks: bool

Enforce bounds checks in shaders, even if the underlying driver doesn’t support doing so natively.

When this is true, wgpu promises that shaders can only read or write the accessible region of a bindgroup’s buffer bindings. If the underlying graphics platform cannot implement these bounds checks itself, wgpu will inject bounds checks before presenting the shader to the platform.

When this is false, wgpu only enforces such bounds checks if the underlying platform provides a way to do so itself. wgpu does not itself add any bounds checks to generated shader code.

Note that wgpu users may try to initialize only those portions of buffers that they anticipate might be read from. Passing false here may allow shaders to see wider regions of the buffers than expected, making such deferred initialization visible to the application.

force_loop_bounding: bool

If false, the caller MUST ensure that all passed shaders do not contain any infinite loops.

If it does, backend compilers MAY treat such a loop as unreachable code and draw conclusions about other safety-critical code paths. This option SHOULD NOT be disabled when running untrusted code.

Implementations

impl ShaderRuntimeChecks

pub fn checked() -> ShaderRuntimeChecks

Creates a new configuration where the shader is fully checked.

pub fn unchecked() -> ShaderRuntimeChecks

Creates a new configuration where none of the checks are performed.

Safety

See the documentation for the set_* methods for the safety requirements of each sub-configuration.

pub unsafe fn all(all_checks: bool) -> ShaderRuntimeChecks

Creates a new configuration where all checks are enabled or disabled. To safely create a configuration with all checks enabled, use ShaderRuntimeChecks::checked.

Safety

See the documentation for the set_* methods for the safety requirements of each sub-configuration.
