Enum ApproximationMethod 

pub enum ApproximationMethod {
    None,
    Simple,
    TehChinL1,
    TehChinKCos,
}

Contour approximation method

Variants

None

Store all contour points (no approximation)

Simple

Compress horizontal, vertical, and diagonal segments (keep only endpoints)

TehChinL1

Apply Teh-Chin chain approximation (L1 distance)

TehChinKCos

Apply Teh-Chin chain approximation (k-cosine curvature)

Trait Implementations

impl Clone for ApproximationMethod

fn clone(&self) -> ApproximationMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApproximationMethod

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

Formats the value using the given formatter.

impl Default for ApproximationMethod

fn default() -> ApproximationMethod

Returns the “default value” for a type.

impl PartialEq for ApproximationMethod

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

impl Copy for ApproximationMethod

impl Eq for ApproximationMethod

impl StructuralPartialEq for ApproximationMethod
