Derive Macro Display_filter 

#[derive(Display_filter)]
{
    // Attributes available to this derive:
    #[name]
    #[parameters]
}

Implements Display for a structure that intends to implement the Filter trait.

Requires the helper attribute #[name = "..."] to tell the name of the filter before its declaration.

If the filter has parameters, the field that holds them must be marked with #[parameters].

Example

#[derive(Debug, FromFilterParameters, Display_filter)]
#[name = "at_least"] // The name of the filter
struct AtLeastFilter {
    #[parameters] // Mark the FilterParameters struct
    args: AtLeastArgs, // A struct that implements `FilterParameters`
}

impl Filter for AtLeastFilter {
    // ...
}
