Trait Implementations

impl Clone for VarSignature

fn clone(&self) -> VarSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VarSignature

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

Formats the value using the given formatter.

impl Display for VarSignature

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

Formats the value using the given formatter.

impl Hash for VarSignature

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 Locational for VarSignature

fn loc(&self) -> Location

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

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

impl NestedDisplay for VarSignature

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

impl PartialEq<VarSignature> for VarSignature

fn eq(&self, other: &VarSignature) -> 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.
