Struct icu_collator::elements::NonPrimary

pub(crate) struct NonPrimary(u32);

The purpose of grouping the non-primary bits into a struct is to allow for a future optimization that specializes code over whether storage for primary weights is needed or not. (I.e. whether to specialize on CollationElement or NonPrimary.)

Implementations

impl NonPrimary

pub fn new(bits: u32) -> Self

Constructor

pub fn bits(&self) -> u32

Get the bits

pub fn secondary(&self) -> u16

Get the secondary weight

pub fn case(&self) -> u16

Get the case bits as the high two bits of a u16

pub fn tertiary(&self) -> u16

Get the tertiary weight as u16 with the high two bits of each half zeroed.

pub fn tertiary_ignorable(&self) -> bool

pub fn quaternary(&self) -> u32

Get the quaternary weight in the original storage bit positions with the other bits set to one.

pub fn tertiary_case_quarternary(&self, mask: u16) -> u16

Get any combination of tertiary, case, and quaternary by mask.

pub fn case_quaternary(&self) -> u16

Trait Implementations

impl Clone for NonPrimary

fn clone(&self) -> NonPrimary

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NonPrimary

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

Formats the value using the given formatter.

impl Default for NonPrimary

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for NonPrimary

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