Trait json_tools::IteratorExt

pub trait IteratorExt: Iterator<Item = Token> {
    fn filter_key_value_by_type(
        self, 
        token_type: TokenType
    ) -> FilterTypedKeyValuePairs<Self>
    where
        Self: Sized,
    { ... }
    fn reader(self, source: Option<&str>) -> TokenReader<Self>
    where
        Self: Sized,
    { ... }
}

Applies convenience constructors to all Iterator<Item=Token> types

Provided methods

Important traits for FilterTypedKeyValuePairs<I>

impl<I> Iterator for FilterTypedKeyValuePairs<I> where
    I: IntoIterator<Item = Token>,  type Item = Token;

fn filter_key_value_by_type(
    self,
    token_type: TokenType
) -> FilterTypedKeyValuePairs<Self> where
    Self: Sized, 

Returns an Iterator which filters key=value pairs, if value.kind matches the given token_type.

It is useful, for example, to get rid of null values on a lexical level.

Important traits for TokenReader<'a, I>

impl<'a, I: IntoIterator<Item = Token>> Read for TokenReader<'a, I>

fn reader(self, source: Option<&str>) -> TokenReader<Self> where
    Self: Sized, 

Returns a TokenReader to produce a byte stream from Token instances

Arguments

• source - an optional, original string from which the tokens were generated. This offers the best performance when serializing tokens, as they can refer to their original &str slice.
