Struct LookupTable 

Source 
pub struct LookupTable<Point> {
    points: [Point; 8],
}
Expand description

Fields§

§points: [Point; 8]

Implementations§

Source§

impl<Point> LookupTable<Point>
where Point: ConditionallySelectable + Group,

Source

pub const SIZE: usize = LUT_SIZE

Number of entries in the lookup table.

Source

pub fn new(p: Point) -> Self

Compute a new lookup table from the given point.

Source

pub fn select(&self, x: i8) -> Point

Given -8 <= x <= 8, returns x * p in constant time.

Source

pub fn select_vartime(&self, x: i8) -> Point

Given -8 <= x <= 8, returns x * p in variable time.
