Derive Macro liquid_derive::ParseFilter

#[derive(ParseFilter)]
{
    // Attributes available to this derive:
    #[filter]
}

Implements ParseFilter.

This is only useful for stateless filters (the most common case). For filters with configurable state, you will need to implement this trait manually.

Requires the #[filter(...)] attribute to define the filter, with the following information: - parameters -> (OPTIONAL) only required if the filter has parameters, the FilterParameters struct - parsed -> the Filter struct

Example

#[derive(Clone, ParseFilter, FilterReflection)]
#[filter(
    name = "slice",  // Required by `FilterReflection`, not `ParseFilter`
    description = "Takes a slice of a given string or array.", // Required by `FilterReflection`, not `ParseFilter`
    parameters(SliceArgs), // The filter has parameters
    parsed(SliceFilter)
)]
pub struct Slice;
