Struct RuntimeParameters

pub struct RuntimeParameters { /* private fields */ }

Runtime reflection of shader parameters for filter chains.

All operations on runtime parameters are atomic and can be done on any thread.

Implementations

impl RuntimeParameters

pub fn new(passes_enabled: usize, parameters: Vec<ParameterMeta>) -> Self

Create a new instance of runtime parameters from a Vec of shader parameters from a ShaderPreset.

pub fn parameter_value(&self, name: &str) -> Option<f32>

Get the value of a runtime parameter

pub fn set_parameter_value(&self, name: &str, new_value: f32) -> Option<f32>

Set a runtime parameter.

This is a relatively slow operation as it will be synchronized across threads. If updating multiple parameters, see RuntimeParameters::update_parameters.

pub fn update_parameters( &self, updater: impl FnOnce(&mut FastHashMap<ShortString, f32>), )

Update multiple runtime parameters atomically through a function.

pub fn parameters(&self) -> Arc<FastHashMap<ShortString, f32>>

Get a reference to the runtime parameters.

pub fn passes_enabled(&self) -> usize

Get the number of passes enabled.

If set from RuntimeParameters::set_passes_enabled from a different thread, it is not guaranteed to be immediately visible.

pub fn set_passes_enabled(&self, count: usize)

Set the number of passes enabled.

This is an atomic operation and is thread-safe.
