Struct icu_collator::elements::CollationElement

pub(crate) struct CollationElement(u64);

A collation element is a 64-bit value.

Bits 63..32 are the primary weight. Bits 31..16 are the secondary weight. Bits 15..14 are the case bits. Bits 13..8 and 5..0 are the (bitwise discontiguous) tertiary weight. Bits 7..6 the quaternary weight.

Trait Implementations

impl Clone for CollationElement

fn clone(&self) -> CollationElement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CollationElement

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

Formats the value using the given formatter.

impl Default for &CollationElement

fn default() -> Self

Returns the “default value” for a type.

impl Default for CollationElement

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CollationElement

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