Struct SpaceAmpStrategy

Source 
pub struct SpaceAmpStrategy(/* private fields */);
Expand description

Tries to find a least-effort-selection of segments to merge to reach a certain space amplification

Implementations§

Source§

impl SpaceAmpStrategy

Source

pub fn new(ratio: f32) -> SpaceAmpStrategy

Creates a new strategy with the given space amp factor.

§Panics

Panics if the space amp factor is < 1.0.
