Struct Tz

pub struct Tz { /* private fields */ }

Timezone indicator.

Examples

use hotfix_encoding::field_access::FieldType;
use hotfix_encoding::field_types::Tz;
use std::time::Duration;

let timezone = Tz::deserialize(b"Z").unwrap();
assert_eq!(timezone, Tz::UTC);
assert_eq!(timezone.offset().1, Duration::from_secs(0));

let timezone = Tz::deserialize(b"+03").unwrap();
assert_eq!(timezone.offset(), (1, Duration::from_secs(3 * 3600)));

let timezone = Tz::deserialize(b"-01").unwrap();
assert_eq!(timezone.offset(), (-1, Duration::from_secs(1 * 3600)));

let timezone = Tz::deserialize(b"+04:30").unwrap();
assert_eq!(timezone.offset(), (1, Duration::from_secs(4 * 3600 + 30 * 60)));

Implementations

impl Tz

pub const UTC: Self

The UTC timezone.

pub fn offset(&self) -> (i32, Duration)

Calculates the offset information of self as compared to UTC. The return value is in the form of a sign (-1, 0, or +1) and a Duration.

pub fn offset_as_secs(&self) -> i32

Returns the raw offset from UTC of self measured in seconds.

Trait Implementations

impl Clone for Tz

fn clone(&self) -> Tz

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tz

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

Formats the value using the given formatter.

impl<'a> FieldType<'a> for Tz

type Error = &'static str

The error type that can arise during deserialization.

type SerializeSettings = ()

A type with values that customize the serialization algorithm, e.g. padding information.

fn serialize_with<B>(&self, buffer: &mut B, _settings: ()) -> usize

where B: Buffer,

Writes self to buffer using custom serialization settings.

fn deserialize(data: &'a [u8]) -> Result<Self, Self::Error>

Parses and deserializes from data.

fn deserialize_lossy(data: &'a [u8]) -> Result<Self, Self::Error>

Like FieldType::deserialize, but it’s allowed to skip some amount of input checking. Invalid inputs might not trigger errors and instead be deserialized as random values.

fn serialize<B>(&self, buffer: &mut B) -> usize

where B: Buffer,

Writes self to buffer using default settings.

fn to_bytes(&self) -> Vec<u8>

Serializes self to a Vec of bytes, allocated on the fly.

fn to_string(&self) -> String

Allocates a String representation of self, using FieldType::to_bytes.

impl Hash for Tz

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Tz

fn eq(&self, other: &Tz) -> 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.
