VariantOffsetsCalculator

icu::time::zone

Struct VariantOffsetsCalculator 

Source 
pub struct VariantOffsetsCalculator { /* private fields */ }
👎Deprecated since 2.1.0: this API is a bad approximation of a time zone database
Expand description

VariantOffsetsCalculator uses data from the data provider to calculate time zone offsets.

Implementations§

Source§

impl VariantOffsetsCalculator

Source

pub const fn new() -> VariantOffsetsCalculatorBorrowed<'static>

Constructs a VariantOffsetsCalculator using compiled data.

✨ Enabled with the compiled_data Cargo feature.

Source

pub fn try_new_with_buffer_provider( provider: &(impl BufferProvider + ?Sized), ) -> Result<VariantOffsetsCalculator, DataError>

A version of Self::new that uses custom data provided by a BufferProvider.

✨ Enabled with the serde feature.

pub fn try_new_unstable( provider: &(impl DataProvider<TimezonePeriodsV1> + ?Sized), ) -> Result<VariantOffsetsCalculator, DataError>

A version of Self::new that uses custom data provided by a DataProvider.

📚 Help choosing a constructor

⚠️ The bounds on provider may change over time, including in SemVer minor releases.
Source

pub fn as_borrowed(&self) -> VariantOffsetsCalculatorBorrowed<'_>

Returns a borrowed version of the calculator that can be queried.

This avoids a small potential indirection cost when querying.
