Struct TzString 

pub struct TzString {
    pub std_abbr: String,
    pub std_utoff: i32,
    pub dst: Option<Dst>,
}

A parsed POSIX TZ string. utoff_* are seconds EAST of UTC (so local = UTC + utoff), already sign-flipped from the POSIX west-positive convention.

Fields

std_abbr: String

std_utoff: i32

dst: Option<Dst>

Implementations

impl TzString

pub fn observe(&self, t: i64) -> Observation

offset/is_dst/abbreviation at UTC instant t, via the POSIX rule. Robust across the year boundary: it materialises the start/end transitions for the years around t, sorts them, and takes the state set by the latest transition at-or-before t.

Trait Implementations

impl Clone for TzString

fn clone(&self) -> TzString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TzString

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

Formats the value using the given formatter.

impl Eq for TzString

impl PartialEq for TzString

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