Struct icu_timezone::provider::names::IanaToBcp47MapV2

pub struct IanaToBcp47MapV2<'data> {
    pub map: ZeroAsciiIgnoreCaseTrie<ZeroVec<'data, u8>>,
    pub bcp47_ids: ZeroVec<'data, TimeZoneBcp47Id>,
    pub bcp47_ids_checksum: u64,
}

A mapping from normal-case IANA time zone identifiers to BCP-47 time zone identifiers.

Multiple IANA time zone IDs can map to the same BCP-47 time zone ID.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Fields

map: ZeroAsciiIgnoreCaseTrie<ZeroVec<'data, u8>>

A map from normal-case IANA time zone identifiers to indexes of BCP-47 time zone identifiers along with a canonical flag. The IANA identifiers are normal-case.

The usize values stored in the trie have the following form:

• Lowest bit: 1 if canonical, 0 if not canonical
• All remaining bits: index into bcp47_ids

For example, in CLDR 44, "Africa/Abidjan" has value 221, which means it is canonical (low bit is 1 == odd number) and the index into bcp47_ids is 110 (221 >> 1).

bcp47_ids: ZeroVec<'data, TimeZoneBcp47Id>

A sorted list of BCP-47 time zone identifiers.

bcp47_ids_checksum: u64

An XxHash64 checksum of Self::bcp47_ids.

Trait Implementations

impl<'data> Clone for IanaToBcp47MapV2<'data>

fn clone(&self) -> IanaToBcp47MapV2<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for IanaToBcp47MapV2<'data>

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

Formats the value using the given formatter.

impl<'data> PartialEq for IanaToBcp47MapV2<'data>

fn eq(&self, other: &IanaToBcp47MapV2<'data>) -> 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.

impl<'a> Yokeable<'a> for IanaToBcp47MapV2<'static>

type Output = IanaToBcp47MapV2<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, IanaToBcp47MapV2<'zf_inner>> for IanaToBcp47MapV2<'zf>

fn zero_from(this: &'zf IanaToBcp47MapV2<'zf_inner>) -> Self

Clone the other C into a struct that may retain references into C.
