Derive Macro AutotuneKey 

#[derive(AutotuneKey)]
{
    // Attributes available to this derive:
    #[autotune]
}

Implements display and initialization for autotune keys.

Helper

Use the #[autotune(anchor)] helper attribute to anchor a numerical value. This groups multiple numerical values into the same bucket.

For now, only an exponential function is supported, and it can be modified with exp. By default, the base is ‘2’ and there are no min or max provided.

Example

#[derive(AutotuneKey, Clone, Debug, PartialEq, Eq, Hash, Serialize, Deserialize)]
pub struct OperationKey {
    #[autotune(name = "Batch Size")]
    batch_size: usize,
    channels: usize,
    #[autotune(anchor(exp(min = 16, max = 1024, base = 2)))]
    height: usize,
    #[autotune(anchor)]
    width: usize,
}
