Struct nalgebra::Unit

pub struct Unit<T> {
    // some fields omitted
}

A wrapper that ensures the undelying algebraic entity has a unit norm.

Use .as_ref() or .unwrap() to obtain the undelying value by-reference or by-move.

Methods

impl<T: Norm> Unit<T>

fn new(v: &T) -> Self

Normalize the given value and return it wrapped on a Unit structure.

fn try_new(v: &T, min_norm: T::NormType) -> Option<Self>

Attempts to normalize the given value and return it wrapped on a Unit structure.

Returns None if the norm was smaller or equal to min_norm.

fn new_and_get(v: T) -> (Self, T::NormType)

Normalize the given value and return it wrapped on a Unit structure and its norm.

fn try_new_and_get(v: T, min_norm: T::NormType) -> Option<(Self, T::NormType)>

Normalize the given value and return it wrapped on a Unit structure and its norm.

Returns None if the norm was smaller or equal to min_norm.

fn renormalize(&mut self) -> T::NormType

Normalizes this value again. This is useful when repeated computations might cause a drift in the norm because of float inaccuracies.

Returns the norm before re-normalization (should be close to 1.0).

impl<T> Unit<T>

fn from_unit_value_unchecked(v: T) -> Self

Wraps the given value, assuming it is already normalized.

This function is not safe because v is not verified to be actually normalized.

fn unwrap(self) -> T

Retrieves the underlying value.
