}

Variants

Explicit

ExplicitNamed

Path in a type definition, where the anonymous lifetime '_ is not allowed.

Optional

Trait Implementations

impl Clone for ParamMode

fn clone(&self) -> ParamMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParamMode

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

Formats the value using the given formatter.

impl PartialEq<ParamMode> for ParamMode

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

impl Copy for ParamMode

impl StructuralPartialEq for ParamMode

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
