Placeholders of the form {KEY} in the template string are replaced by the corresponding values supplied via ShaderTemplate::instantiate.

Fields

template: String

The raw template source with {KEY} placeholders.

Implementations

impl ShaderTemplate

pub fn new(template: impl Into<String>) -> Self
