Struct ContainerDimensions 

pub struct ContainerDimensions { /* private fields */ }

The size of the container to draw, checked against the two size gates.

A validated pair rather than two loose integers: the only way to obtain one is ContainerDimensions::new, which refuses anything the loader would refuse, so no code downstream has to re-check a width or a height. A larger container carries more — capacity is a straight function of its pixel count — but every size this type admits is one a receiver can load and one whose texture feeds the hash gate the same octave the default does; see [crate::generate::texture] for why enlarging is safe rather than merely tolerated.

Implementations

impl ContainerDimensions

pub fn new(width: u32, height: u32) -> Result<Self, GenerateError>

A dimensions pair, if it clears both gates a loaded container is held to.

Errors

Returns GenerateError::DimensionsOutOfRange when either side is below MIN_CONTAINER_SIDE, or when the two multiply to more than MAX_CONTAINER_PIXELS. The product is taken in u64 so that two large sides cannot wrap into a small count and slip past the ceiling.

pub fn width(&self) -> u32

Width of the container, in pixels.

pub fn height(&self) -> u32

Height of the container, in pixels.
