Trait Implementations

impl Clone for Vars

fn clone(&self) -> Vars

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Vars

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

Formats the value using the given formatter.

impl Display for Vars

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

Formats the value using the given formatter.

impl From<Vars> for Vec<VarSignature>

fn from(item: Vars) -> Vec<VarSignature>

Converts to this type from the input type.

impl Hash for Vars

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Index<usize> for Vars

type Output = VarSignature

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Vars

fn index_mut(&mut self, idx: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl IntoIterator for Vars

type Item = VarSignature

The type of the elements being iterated over.

type IntoIter = IntoIter<<Vars as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Locational for Vars

fn loc(&self) -> Location

NOTE: loc cannot be treated as a light method when self is a large grammatical element. If possible, delay the computation by passing &impl Locational or other means.

fn ln_begin(&self) -> Option<u32>

1-origin

fn ln_end(&self) -> Option<u32>

fn col_begin(&self) -> Option<u32>

0-origin

fn col_end(&self) -> Option<u32>

impl NestedDisplay for Vars

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

impl PartialEq for Vars

fn eq(&self, other: &Vars) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
