Struct HeightmapView 

pub struct HeightmapView<'a> {
    pub format: HeightmapFormat,
    pub rgb: &'a [u8],
    pub width: u32,
    pub height: u32,
}

Zero-copy borrowed view over an encoded RGB heightmap.

Holds a &[u8] referencing the source bytes and lazily yields decoded elevations via Self::iter / Self::get — no Vec<f32> is materialised unless the caller explicitly asks via Self::to_vec or Self::decode_into.

Fields

format: HeightmapFormat

Format used to interpret the bytes.

rgb: &'a [u8]

Raw RGB bytes (width * height * 3 bytes, row-major).

width: u32

Image width in pixels.

height: u32

Image height in pixels.

Implementations

impl<'a> HeightmapView<'a>

pub fn new( format: HeightmapFormat, rgb: &'a [u8], width: u32, height: u32, ) -> Self

Wrap an RGB buffer. Asserts rgb.len() == width * height * 3.

pub fn len(&self) -> usize

Number of pixels.

pub fn is_empty(&self) -> bool

true if the view has zero pixels.

pub fn get(&self, x: u32, y: u32) -> f32

Sample the elevation at (x, y) in pixels.

pub fn iter(&self) -> impl Iterator<Item = f32> + '_

Iterator over decoded elevations in row-major order.

pub fn decode_into(&self, out: &mut [f32])

Decode the entire view into a caller-owned buffer.

pub fn to_vec(&self) -> Vec<f32>

Decode into a freshly allocated Vec<f32>.
