Enum OffsetToTai 

pub enum OffsetToTai {
    Fixed(i64),
    Contextual,
}

Relationship between a time scale and TAI.

The defining invariant is:

T_tai = T_scale + offset

Variants

• Fixed: constant offset (no external dependencies)
• Contextual: depends on runtime leap-second information

Contextual scales require a leap-second provider for correct conversion.

Variants

Fixed(i64)

Constant offset relative to TAI.

Contextual

Offset depends on external context (e.g. leap seconds).

Implementations

impl OffsetToTai

pub const fn fixed(self) -> Option<i64>

Returns the fixed offset in nanoseconds.

pub const fn is_contextual(self) -> bool

Returns true for scales that require runtime context (UTC, GLONASS).

pub const fn is_fixed(self) -> bool

Returns true for scale with a fixed TAI offset.

Trait Implementations

impl Clone for OffsetToTai

fn clone(&self) -> OffsetToTai

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OffsetToTai

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

Formats the value using the given formatter.

impl Hash for OffsetToTai

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 OffsetToTai

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