Enum RetrievalMode 

pub enum RetrievalMode {
    External,
    List,
    CComp,
    Tree,
    FloodFill,
}

Contour retrieval modes for hierarchy-based contour detection.

Variants

External

Retrieves only the extreme outer contours.

List

Retrieves all contours and creates a flat list.

CComp

Retrieves all contours and organizes them into two-level hierarchies (external and holes).

Tree

Retrieves all contours and builds a full hierarchy tree.

FloodFill

Flood fill retrieval mode.

Trait Implementations

impl Clone for RetrievalMode

fn clone(&self) -> RetrievalMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RetrievalMode

impl Debug for RetrievalMode

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

Formats the value using the given formatter.

impl Eq for RetrievalMode

impl PartialEq for RetrievalMode

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