Struct PyTypeTableHandle 

pub struct PyTypeTableHandle { /* private fields */ }

Handle to a CCDB type table, exposing metadata and fetch APIs to Python.

Attributes

name : str Table name without directory components. id : int Unique table identifier in CCDB. meta : TypeTableMeta Metadata describing row/column counts and comments.

Implementations

impl PyTypeTableHandle

pub fn name(&self) -> &str

str: Table name (without directory components).

pub fn id(&self) -> i64

int: Numeric identifier of the table in CCDB.

pub fn meta(&self) -> PyTypeTableMeta

TypeTableMeta: Metadata such as row counts and comments.

pub fn full_path(&self) -> String

str: Absolute path to this table.

pub fn columns(&self) -> PyResult<Vec<PyColumnMeta>>

columns(self)

Returns

listColumnMeta Metadata for each column in order.

pub fn fetch( &self, runs: Option<Vec<RunNumber>>, variation: Option<String>, timestamp: Option<Bound<'_, PyAny>>, ) -> PyResult<BTreeMap<RunNumber, PyData>>

fetch(self, *, runs=None, variation=None, timestamp=None)

Parameters

runs : list[int] | None, optional Run numbers to query; defaults to run 0 when omitted. variation : str | None, optional Variation branch to resolve (default “default”). timestamp : datetime | str | None, optional Timestamp used to select historical assignments.

Returns

dict[int, Data] Mapping of run number to fetched dataset.

pub fn fetch_run_period( &self, run_period: &str, rest_version: Option<Bound<'_, PyAny>>, variation: Option<String>, timestamp: Option<Bound<'_, PyAny>>, ) -> PyResult<BTreeMap<RunNumber, PyData>>

fetch_run_period(self, *, run_period, rest_version=None, variation=None, timestamp=None)

Parameters

run_period : str The short string of the corresponding GlueX run period (e.g. “S17”, “F18”) rest_version : int | datetime | None, optional The REST version or explicit timestamp to use when resolving a time stamp. variation : str | None, optional Variation branch to resolve (default “default”). timestamp : datetime | str | None, optional Timestamp used to select historical assignments. This will override timestamp from the REST version if provided

Returns

dict[int, Data] Mapping of run number to fetched dataset.

type Layout = <<PyTypeTableHandle as PyClassImpl>::BaseNativeType as PyClassBaseType>::Layout<PyTypeTableHandle>

Description of how this class is laid out in memory

type BaseType = PyAny

Base class

type ThreadChecker = ThreadCheckerImpl

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
