Struct TimeZoneInfo

pub struct TimeZoneInfo {
    pub id: Option<TimeZoneId>,
    pub total_offset_at_time: Option<i64>,
    pub in_dst_at_time: Option<bool>,
    /* private fields */
}

Describes a Time Zone’s properties at a particular moment in time.

TODO(https://fxbug.dev/42162409): Additional fields with a breakdown of offsets and DST status.

Fields

id: Option<TimeZoneId>

The time zone’s IANA ID.

total_offset_at_time: Option<i64>

The total offset (including Daylight Savings, if the time zone is in Daylight Savings Time) from UTC at the queried time (at_time). If the time zone is ahead of UTC, this will be a positive value; if behind UTC, a negative value.

in_dst_at_time: Option<bool>

Indicates whether the time zone is in Daylight Savings Time at the queried time (at_time).

Trait Implementations

impl Clone for TimeZoneInfo

fn clone(&self) -> TimeZoneInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeZoneInfo

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

Formats the value using the given formatter.

impl<D> Decode<TimeZoneInfo, D> for TimeZoneInfo

where D: ResourceDialect,

fn new_empty() -> TimeZoneInfo

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for TimeZoneInfo

fn default() -> TimeZoneInfo

Returns the “default value” for a type.

impl<D> Encode<TimeZoneInfo, D> for &TimeZoneInfo

where D: ResourceDialect,

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl PartialEq for TimeZoneInfo

fn eq(&self, other: &TimeZoneInfo) -> 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 TypeMarker for TimeZoneInfo

type Owned = TimeZoneInfo

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for TimeZoneInfo

type Borrowed<'a> = &'a TimeZoneInfo

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<TimeZoneInfo as TypeMarker>::Owned, ) -> <TimeZoneInfo as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
