#[must_use] fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for AccessType

fn clone(&self) -> AccessType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for AccessType

fn default() -> Self

Returns the "default value" for a type.

impl Copy for AccessType

impl Debug for AccessType

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

Formats the value using the given formatter.
