Enum Tile 

#[non_exhaustive]
pub enum Tile {
    Empty,
    Solid,
    Platform,
    Custom(u8),
}

What fills one tile. New kinds may come, so matches need a _ arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Air.

Solid

Blocks from every side; plain ground (Surface::DEFAULT), climbable.

Platform

Blocks only from above, and only while not dropping through.

Custom(u8)

Your game’s own tile, by a number of your choosing: spikes, water, a checkpoint, the goal, ice. The movement treats it as air unless Level::define says it is solid or a one-way platform; find the ones the character touches with Level::tiles_touching.

Unlike a CustomId, the number is not a name hash, on purpose: one byte per tile keeps the grid small, and the numbers belong to the level, which one game builds. A crate that ships a tile kind (spikes, water) takes its number as a parameter, so the game hands out the numbers and two crates never collide.
