Enum syn::punctuated::Pair
source · [−]pub enum Pair<T, P> {
Punctuated(T, P),
End(T),
}Expand description
A single syntax tree node of type T followed by its trailing punctuation
of type P if any.
Refer to the module documentation for details about punctuated sequences.

End(T)
Implementations
sourceimpl<T, P> Pair<T, P>
impl<T, P> Pair<T, P>
sourcepub fn into_value(self) -> T
pub fn into_value(self) -> T
Extracts the syntax tree node from this punctuated pair, discarding the following punctuation.
sourcepub fn value_mut(&mut self) -> &mut T
pub fn value_mut(&mut self) -> &mut T
Mutably borrows the syntax tree node from this punctuated pair.
sourcepub fn punct(&self) -> Option<&P>
pub fn punct(&self) -> Option<&P>
Borrows the punctuation from this punctuated pair, unless this pair is the final one and there is no trailing punctuation.
sourcepub fn new(t: T, p: Option<P>) -> Self
pub fn new(t: T, p: Option<P>) -> Self
Creates a punctuated pair out of a syntax tree node and an optional following punctuation.
sourcepub fn into_tuple(self) -> (T, Option<P>)
pub fn into_tuple(self) -> (T, Option<P>)
Produces this punctuated pair as a tuple of syntax tree node and optional following punctuation.
