Trait ParamSource 

pub trait ParamSource {
    // Required method
    fn get(&mut self, name: &str) -> Option<Param>;
}

Supplies a stage’s parameters on demand, by name. None means “not mine” (the runtime leaves the param unset — useful when a source only owns a shard).

Required Methods

fn get(&mut self, name: &str) -> Option<Param>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl ParamSource for HashMap<String, Param>

A HashMap<String, Param> is a source (mixed f32 / packed).

fn get(&mut self, name: &str) -> Option<Param>

impl ParamSource for HashMap<String, Vec<f32>>

A HashMap<String, Vec<f32>> is a source (dense f32; clones on read).

fn get(&mut self, name: &str) -> Option<Param>

Implementors

impl<F> ParamSource for F

where F: FnMut(&str) -> Option<Param>,

Any FnMut(&str) -> Option<Param> is a source — adapt an existing loader inline without defining a type.
