Trait Implementations

impl Clone for TokenStream

fn clone(&self) -> TokenStream

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Compare<TokenStream> for TokenStream

fn compare(&self, t: TokenStream) -> CompareResult

Compares self to another value for equality

fn compare_no_case(&self, t: TokenStream) -> CompareResult

Compares self to another value for equality independently of the case.

impl Debug for TokenStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TokenStream

fn default() -> TokenStream

Returns the “default value” for a type.

impl Input for TokenStream

type Item = Token

The current input type is a sequence of that Item type.

type Iter = IntoIter<Token>

An iterator over the input type, producing the item

type IterIndices = Enumerate<<TokenStream as Input>::Iter>

An iterator over the input type, producing the item and its byte position If we’re iterating over &str, the position corresponds to the byte index of the character

fn input_len(&self) -> usize

Calculates the input length, as indicated by its name, and the name of the trait itself

fn take(&self, index: usize) -> Self

Returns a slice of index bytes. panics if index > length

fn take_from(&self, index: usize) -> Self

Returns a slice starting at index bytes. panics if index > length

fn take_split(&self, index: usize) -> (Self, Self)

Split the stream at the index byte offset. panics if index > length

fn position<P>(&self, predicate: P) -> Option<usize>

where P: Fn(Self::Item) -> bool,

Returns the byte position of the first element satisfying the predicate

fn iter_elements(&self) -> Self::Iter

Returns an iterator over the elements

fn iter_indices(&self) -> Self::IterIndices

Returns an iterator over the elements and their byte offsets

fn slice_index(&self, count: usize) -> Result<usize, Needed>

Get the byte offset from the element’s position in the stream

fn split_at_position<P, E>(&self, predicate: P) -> Result<(Self, Self), Err<E>>

where E: ParseError<Self>, P: Fn(Self::Item) -> bool,

Looks for the first element of the input type for which the condition returns true, and returns the input up to this position.

fn split_at_position1<P, E>( &self, predicate: P, e: ErrorKind, ) -> Result<(Self, Self), Err<E>>

where E: ParseError<Self>, P: Fn(Self::Item) -> bool,

Looks for the first element of the input type for which the condition returns true and returns the input up to this position.

fn split_at_position_complete<P, E>( &self, predicate: P, ) -> Result<(Self, Self), Err<E>>

where E: ParseError<Self>, P: Fn(Self::Item) -> bool,

Looks for the first element of the input type for which the condition returns true, and returns the input up to this position.

fn split_at_position1_complete<P, E>( &self, predicate: P, e: ErrorKind, ) -> Result<(Self, Self), Err<E>>

where E: ParseError<Self>, P: Fn(Self::Item) -> bool,

Looks for the first element of the input type for which the condition returns true and returns the input up to this position.

fn split_at_position_mode<OM, P, E>( &self, predicate: P, ) -> Result<(Self, <<OM as OutputMode>::Output as Mode>::Output<Self>), Err<E, <<OM as OutputMode>::Error as Mode>::Output<E>>>

where OM: OutputMode, E: ParseError<Self>, P: Fn(Self::Item) -> bool,

mode version of split_at_position

fn split_at_position_mode1<OM, P, E>( &self, predicate: P, e: ErrorKind, ) -> Result<(Self, <<OM as OutputMode>::Output as Mode>::Output<Self>), Err<E, <<OM as OutputMode>::Error as Mode>::Output<E>>>

where OM: OutputMode, E: ParseError<Self>, P: Fn(Self::Item) -> bool,

mode version of split_at_position
