Enum ContractionType 

pub enum ContractionType {
    Divisorial,
    Small,
    FiberType,
}

Classification of the contraction associated with an extremal ray.

Variants

Divisorial

Contracts a divisor to a lower-dimensional variety.

Small

Small contraction: flipping locus has codimension ≥ 2.

FiberType

Fiber type: target has strictly smaller dimension.

Trait Implementations

impl Clone for ContractionType

fn clone(&self) -> ContractionType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractionType

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

Formats the value using the given formatter.

impl PartialEq for ContractionType

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