Struct FeatureMatch 

pub struct FeatureMatch { /* private fields */ }

One descriptor correspondence from a query feature to a train feature.

Implementations

impl FeatureMatch

pub fn try_new( query_index: usize, train_index: usize, distance: f32, ) -> VisionResult<Self>

Creates a correspondence with a finite non-negative distance.

pub fn validate( self, query_count: usize, train_count: usize, ) -> VisionResult<Self>

Validates both indices against their feature collections.

pub const fn query_index(self) -> usize

Returns the query descriptor row index.

pub const fn train_index(self) -> usize

Returns the train descriptor row index.

pub const fn distance(self) -> f32

Returns the descriptor distance; smaller is a better match.

Trait Implementations

impl Clone for FeatureMatch

fn clone(&self) -> FeatureMatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureMatch

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

Formats the value using the given formatter.

impl PartialEq for FeatureMatch

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