Implementations

impl FieldModifier

pub fn into_owned(self) -> FieldModifier

Copy the structure and clone the original values if it’s not owned.

This is always a deep copy of the structure.

Trait Implementations

impl Clone for FieldModifier

fn clone(&self) -> FieldModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldModifier

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

Formats the value using the given formatter.

impl IntoOwned for FieldModifier

type Owned = FieldModifier

The type after obtaining ownership, should be the same as before but with static lifetime.

fn into_owned(self) -> Self::Owned

Copy the structure and clone the original values if it’s not owned.

impl PartialEq for FieldModifier

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

Tests for self and other values to be equal, and is used by ==.

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

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