Struct PartitionRef 

pub struct PartitionRef {
    pub asset: String,
    pub coin: String,
    pub month: String,
}

A fully-qualified reference to a single partition.

A partition is one (asset, coin, month) Parquet object, e.g. gold_ohlcv_1m / BTC / 2025-09.

Fields

asset: String

Dataset name, e.g. gold_ohlcv_1m.

coin: String

Coin symbol, e.g. BTC.

month: String

Partition month, YYYY-MM.

Implementations

impl PartitionRef

pub fn new( asset: impl Into<String>, coin: impl Into<String>, month: impl Into<String>, ) -> Result<Self, TesseraError>

Create a reference, validating the month format.

Errors

Returns TesseraError::InvalidArgument when month is not YYYY-MM.

pub fn object_key(&self) -> String

The object-storage key layout: {asset}/coin={COIN}/month={YYYY-MM}.parquet.

Trait Implementations

impl Clone for PartitionRef

fn clone(&self) -> PartitionRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionRef

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

Formats the value using the given formatter.

impl Eq for PartitionRef

impl Hash for PartitionRef

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 PartitionRef

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