Struct IanaToBcp47Map

pub struct IanaToBcp47Map<'data> {
    pub map: ZeroAsciiIgnoreCaseTrie<ZeroVec<'data, u8>>,
    pub bcp47_ids: ZeroVec<'data, TimeZone>,
}

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, TimeZone>

A list of BCP-47 time zone identifiers, sorted by canonical IANA ID.

Trait Implementations

impl<'data> Clone for IanaToBcp47Map<'data>

fn clone(&self) -> IanaToBcp47Map<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for IanaToBcp47Map<'data>

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

Formats the value using the given formatter.

impl<'de, 'data> Deserialize<'de> for IanaToBcp47Map<'data>

where 'de: 'data,

fn deserialize<__D>( __deserializer: __D, ) -> Result<IanaToBcp47Map<'data>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MaybeAsVarULE for IanaToBcp47Map<'_>

type EncodedStruct = [()]

The VarULE type for this data struct, or [()] if it cannot be represented as VarULE.

impl<'data> PartialEq for IanaToBcp47Map<'data>

fn eq(&self, other: &IanaToBcp47Map<'data>) -> 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.

impl<'a> Yokeable<'a> for IanaToBcp47Map<'static>

type Output = IanaToBcp47Map<'a>

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

fn transform(&'a self) -> &'a <IanaToBcp47Map<'static> as Yokeable<'a>>::Output

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

fn transform_owned(self) -> <IanaToBcp47Map<'static> as Yokeable<'a>>::Output

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

unsafe fn make( this: <IanaToBcp47Map<'static> as Yokeable<'a>>::Output, ) -> IanaToBcp47Map<'static>

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 <IanaToBcp47Map<'static> as Yokeable<'a>>::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, IanaToBcp47Map<'zf_inner>> for IanaToBcp47Map<'zf>

fn zero_from(this: &'zf IanaToBcp47Map<'zf_inner>) -> IanaToBcp47Map<'zf>

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