Trait cucumber::codegen::ParametersProvider

pub trait ParametersProvider<Input> {
    type Item: AsChar;
    type Value: InputIter
   where
        <Self::Value as InputIter>::Item == Self::Item;

    fn get(&self, input: &Input) -> Option<Self::Value>;
}

Available on crate feature macros only.

Provider of custom Parameters.

Required Associated Types

type Item: AsChar

<Valueas[InputIter]>::Item.

type Value: InputIter
where
    <Self::Value as InputIter>::Item == Self::Item

Value matcher to be used in a Regex.

Usually, a Parameter is represented by a single Regex capturing group. In case there are multiple capturing groups, they will be named like __{parameter_id}_{group_id}. This is done to identify multiple capturing groups related to a single Parameter.

Required Methods

fn get(&self, input: &Input) -> Option<Self::Value>

Returns a Value matcher corresponding to the given input, if any.

type Item = char

type Value = &'p str
