Struct FuzzyFinder

pub struct FuzzyFinder { /* private fields */ }

FuzzyFinder blazing fast for most places on earth, use a preindex data. Not work for places around borders.

FuzzyFinder store all preindex’s tiles data in a HashMap, It iterate all zoom levels for input’s longitude and latitude to build map key to to check if in map.

It’s is very fast and use about 400ns to check if has preindex. It work for most places on earth and here is a quick loop of preindex data:

Implementations

impl FuzzyFinder

pub fn from_pb(tzs: PreindexTimezones) -> Self

pub fn get_tz_name(&self, lng: f64, lat: f64) -> &str

Retrieves the time zone name for the given longitude and latitude.

Arguments

• lng - Longitude
• lat - Latitude

Example:

use tzf_rs::FuzzyFinder;

let finder = FuzzyFinder::new();
assert_eq!("Asia/Shanghai", finder.get_tz_name(116.3883, 39.9289));

Panics

• Panics if lng or lat is out of range.
• Panics if lng or lat is not a number.

pub fn get_tz_names(&self, lng: f64, lat: f64) -> Vec<&str>

pub fn data_version(&self) -> &str

Gets the version of the data used by this FuzzyFinder.

Returns

The version of the data used by this FuzzyFinder as a &str.

Example:

use tzf_rs::FuzzyFinder;

let finder = FuzzyFinder::new();
println!("{:?}", finder.data_version());

pub fn new() -> Self

Creates a new, empty FuzzyFinder.

use tzf_rs::FuzzyFinder;

let finder = FuzzyFinder::default();

Trait Implementations

impl Default for FuzzyFinder

fn default() -> Self

Creates a new, empty FuzzyFinder.

use tzf_rs::FuzzyFinder;

let finder = FuzzyFinder::default();
