Trait crossref::query::CrossrefQueryParam

pub trait CrossrefQueryParam {
    fn param_key(&self) -> Cow<str>;
    fn param_value(&self) -> Option<Cow<str>>;

    fn param(&self) -> Cow<str> { ... }
}

a trait used to capture parameters for the query string of the crossref api

Required methods

fn param_key(&self) -> Cow<str>

the key name of the parameter in the query string

fn param_value(&self) -> Option<Cow<str>>

the value of the parameter, if any

Implementations on Foreign Types

impl CrossrefQueryParam for Vec<FacetCount>

fn param_key(&self) -> Cow<str>

fn param_value(&self) -> Option<Cow<str>>

impl<T: Filter> CrossrefQueryParam for Vec<T>

fn param_key(&self) -> Cow<str>

always use filter as the key

fn param_value(&self) -> Option<Cow<str>>

filters are multi value and values are concat with ,
