Implementations

impl SpecializedLayout

pub fn stack_size(&self) -> usize

Get the stack space needed for this specialized value

pub fn alignment(&self) -> usize

Get the alignment requirement for this specialized value

Trait Implementations

impl Clone for SpecializedLayout

fn clone(&self) -> SpecializedLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecializedLayout

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

Formats the value using the given formatter.

impl PartialEq for SpecializedLayout

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