pub fn is_final(self) -> bool

Trait Implementations

impl Clone for NewBlockState

fn clone(&self) -> NewBlockState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NewBlockState

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

Formats the value using the given formatter.

impl PartialEq<NewBlockState> for NewBlockState

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