Struct icu_collator::elements::NonPrimary

source ·
pub(crate) struct NonPrimary(u32);
Expand description

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§

source§

impl NonPrimary

source

pub fn new(bits: u32) -> Self

Constructor

source

pub fn bits(&self) -> u32

Get the bits

source

Get the secondary weight

source

pub fn case(&self) -> u16

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

source

pub fn tertiary(&self) -> u16

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

source

pub fn tertiary_ignorable(&self) -> bool

source

pub fn quaternary(&self) -> u32

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

source

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

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

impl PartialEq for NonPrimary

source§

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