Struct PropertyProfile 

pub struct PropertyProfile { /* private fields */ }

A pre-computed set of string column groupings derived from a representative sample of tiles.

Building a profile once from sample tiles avoids re-running the expensive MinHash similarity analysis on every subsequent tile; the profile’s pre-computed string groups are applied directly during the grouping step instead.

Profiles from multiple samples are combined with PropertyProfile::merge, which takes the union of both sets of string groups.

Implementations

impl PropertyProfile

pub fn from_sample(properties: &[StagedProperty]) -> Self

Build a profile from a sample of staged properties.

Runs MinHash similarity analysis over all string columns and records which column names should be grouped into shared dictionaries.

pub fn merge(self, other: &Self) -> Self

Merge two profiles by taking the union of their string groups.

Groups that share at least one column name are merged together. Groups already present in self are not duplicated.

Trait Implementations

impl Clone for PropertyProfile

fn clone(&self) -> PropertyProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyProfile

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

Formats the value using the given formatter.

impl PartialEq for PropertyProfile

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