Struct CostModel 

pub struct CostModel {
    pub sub: Cost,
    pub open: Cost,
    pub extend: Cost,
}

Different cost models. All values must be non-negative.

Fields

sub: Cost

Substitution cost, (> 0)

TODO: Support -infinity to disallow substitutions entirely.

open: Cost

Gap open cost (>= 0)

When 0, gap cost is linear.

extend: Cost

Gap extend cost (> 0)

Implementations

impl CostModel

pub fn unit() -> Self

pub fn is_unit(&self) -> bool

pub fn linear(sub: Cost, indel: Cost) -> Self

pub fn is_linear(&self) -> bool

pub fn affine(sub: Cost, open: Cost, extend: Cost) -> Self

pub fn is_affine(&self) -> bool

pub fn sub(&self) -> Cost

The cost of a substitution.

pub fn maybe_sub(&self) -> Option<Cost>

The cost of a substitution, or None if not allowed.

pub fn ins(&self, len: I) -> Cost

The cost of an insertion of given length.

pub fn del(&self, len: I) -> Cost

The cost of a deletion of given length.

Trait Implementations

impl Clone for CostModel

fn clone(&self) -> CostModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CostModel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CostModel

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CostModel

fn eq(&self, other: &CostModel) -> 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 Serialize for CostModel

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
