Struct Btic 

pub struct Btic { /* private fields */ }

A Binary Temporal Interval Codec value.

Represents a half-open temporal interval [lo, hi) in milliseconds since the Unix epoch (1970-01-01T00:00:00.000Z), with per-bound granularity and certainty metadata packed into a 64-bit meta word.

The 24-byte packed canonical form supports memcmp-based ordering for B-tree and LSM key storage.

Implementations

impl Btic

pub fn new(lo: i64, hi: i64, meta: u64) -> Result<Self, BticError>

Construct a new BTIC value, validating all invariants (INV-1 through INV-7).

pub fn validate(&self) -> Result<(), BticError>

Validate all BTIC invariants on this value.

pub fn build_meta( lo_gran: Granularity, hi_gran: Granularity, lo_cert: Certainty, hi_cert: Certainty, ) -> u64

Build a meta word from granularity and certainty values.

pub fn lo_granularity(&self) -> Granularity

Lower bound granularity.

pub fn hi_granularity(&self) -> Granularity

Upper bound granularity.

pub fn lo_certainty(&self) -> Certainty

Lower bound certainty.

pub fn hi_certainty(&self) -> Certainty

Upper bound certainty.

pub fn lo(&self) -> i64

Lower bound in milliseconds since epoch. i64::MIN means -infinity.

pub fn hi(&self) -> i64

Upper bound in milliseconds since epoch. i64::MAX means +infinity.

pub fn meta(&self) -> u64

Raw meta word.

pub fn duration_ms(&self) -> Option<i64>

Duration in milliseconds. None if either bound is infinite.

pub fn is_instant(&self) -> bool

True if this is an instant (one millisecond wide).

pub fn is_unbounded(&self) -> bool

True if either bound is infinite.

pub fn is_finite(&self) -> bool

True if both bounds are finite.

Trait Implementations

impl Eq for Btic

impl Hash for Btic

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,

impl Ord for Btic

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

impl PartialEq for Btic

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
