Struct Epoch 

pub struct Epoch(/* private fields */);

Trait Implementations

impl Add for Epoch

type Output = Epoch

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Add<usize> for Epoch

type Output = Epoch

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Self::Output

Performs the + operation.

impl AddAssign for Epoch

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Bytes for Epoch

const IS_NATIVE_LAYOUT: bool

Whether the byte representation from to_bytes is identical to the in-memory representation of Self. When true, bulk operations can use memcpy instead of per-element deserialization.

type Array = <u16 as Bytes>::Array

The byte array type returned by to_bytes. For fixed-size types, this is [u8; N] where N is the size of the type.

fn to_bytes(&self) -> Self::Array

Serializes this value to bytes.

fn from_bytes(bytes: &[u8]) -> Result<Self>

Deserializes a value from bytes.

fn clone(&self) -> Epoch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Epoch

impl Debug for Epoch

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Epoch

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

Formats the value using the given formatter.

impl Div<usize> for Epoch

type Output = Epoch

The resulting type after applying the / operator.

fn div(self, rhs: usize) -> Self::Output

Performs the / operation.

impl Eq for Epoch

impl Formattable for Epoch

fn write_to(&self, buf: &mut Vec<u8>)

Write formatted UTF-8 bytes. Primary method — all others derive from it.

fn fmt_into(&self, f: &mut String)

Write to a String via write_to.

fn fmt_csv(&self, f: &mut String) -> Result<(), Error>

Write in CSV format. Override for types needing CSV escaping (e.g., quoting commas).

fn fmt_json(&self, buf: &mut Vec<u8>)

Write in JSON format. Override for types needing JSON wrapping (e.g., string quotes).

impl From<Epoch> for usize

fn from(value: Epoch) -> Self

Converts to this type from the input type.

impl From<Epoch> for f64

fn from(value: Epoch) -> Self

Converts to this type from the input type.

impl From<Height> for Epoch

fn from(value: Height) -> Self

Converts to this type from the input type.

impl From<f64> for Epoch

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<u16> for Epoch

fn from(value: u16) -> Self

Converts to this type from the input type.

impl From<usize> for Epoch

fn from(value: usize) -> Self

Converts to this type from the input type.

impl FromCoarserIndex<Epoch> for Height

fn min_from(coarser: Epoch) -> usize

Returns the minimum fine-grained index represented by the coarse index.

fn max_from_(coarser: Epoch) -> usize

Returns the maximum fine-grained index represented by the coarse index. Note: May exceed actual data length - use max_from for bounded results.

fn max_from(coarser: T, len: usize) -> usize

Returns the maximum fine-grained index, bounded by the data length. Returns 0 if len is 0 (empty data).

fn inclusive_range_from(coarser: T, len: usize) -> RangeInclusive<usize>

where T: Clone,

Returns the inclusive range of fine-grained indices for the coarse index. Returns an empty range (1..=0) if len is 0.

impl JsonSchema for Epoch

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for Epoch
