[][src]Struct syn::punctuated::Punctuated

pub struct Punctuated<T, P> { /* fields omitted */ }

A punctuated sequence of syntax tree nodes of type T separated by punctuation of type P.

Refer to the module documentation for details about punctuated sequences.

Methods

impl<T, P> Punctuated<T, P>
[src]

Creates an empty punctuated sequence.

Determines whether this punctuated sequence is empty, meaning it contains no syntax tree nodes or punctuation.

Returns the number of syntax tree nodes in this punctuated sequence.

This is the number of nodes of type T, not counting the punctuation of type P.

Borrows the first punctuated pair in this sequence.

Borrows the last punctuated pair in this sequence.

Mutably borrows the last punctuated pair in this sequence.

Important traits for Iter<'a, T>

Returns an iterator over borrowed syntax tree nodes of type &T.

Important traits for IterMut<'a, T>

Returns an iterator over mutably borrowed syntax tree nodes of type &mut T.

Important traits for Pairs<'a, T, P>

Returns an iterator over the contents of this sequence as borrowed punctuated pairs.

Important traits for PairsMut<'a, T, P>

Returns an iterator over the contents of this sequence as mutably borrowed punctuated pairs.

Important traits for IntoPairs<T, P>

Returns an iterator over the contents of this sequence as owned punctuated pairs.

Appends a syntax tree node onto the end of this punctuated sequence. The sequence must previously have a trailing punctuation.

Use push instead if the punctuated sequence may or may not already have trailing punctuation.

Panics

Panics if the sequence does not already have a trailing punctuation when this method is called.

Appends a trailing punctuation onto the end of this punctuated sequence. The sequence must be non-empty and must not already have trailing punctuation.

Panics

Panics if the sequence is empty or already has a trailing punctuation.

Removes the last punctuated pair from this sequence, or None if the sequence is empty.

Determines whether this punctuated sequence ends with a trailing punctuation.

Returns true if either this Punctuated is empty, or it has a trailing punctuation.

Equivalent to punctuated.is_empty() || punctuated.trailing_punct().

Appends a syntax tree node onto the end of this punctuated sequence.

If there is not a trailing punctuation in this sequence when this method is called, the default value of punctuation type P is inserted before the given value of type T.

Inserts an element at position index.

Panics

Panics if index is greater than the number of elements previously in this punctuated sequence.

Parses zero or more occurrences of T separated by punctuation of type P, with optional trailing punctuation.

Parsing continues until the end of this parse stream. The entire content of this parse stream must consist of T and P.

This function is available if Syn is built with the "parsing" feature.

Parses zero or more occurrences of T using the given parse function, separated by punctuation of type P, with optional trailing punctuation.

Like parse_terminated, the entire content of this stream is expected to be parsed.

This function is available if Syn is built with the "parsing" feature.

Parses one or more occurrences of T separated by punctuation of type P, not accepting trailing punctuation.

Parsing continues as long as punctuation P is present at the head of the stream. This method returns upon parsing a T and observing that it is not followed by a P, even if there are remaining tokens in the stream.

This function is available if Syn is built with the "parsing" feature.

Parses one or more occurrences of T using the given parse function, separated by punctuation of type P, not accepting trailing punctuation.

Like parse_separated_nonempty, may complete early without parsing the entire content of this stream.

This function is available if Syn is built with the "parsing" feature.
