impl Clone for ContextModifier

fn clone(&self) -> ContextModifier

Returns a copy of the value.

Performs copy-assignment from source.

impl Debug for ContextModifier

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

Formats the value using the given formatter.

impl Display for ContextModifier

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

impl Hash for ContextModifier

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,

impl PartialEq<ContextModifier> for ContextModifier

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