Enum Filter 

pub enum Filter {
    Crop,
    Gay,
    Metal,
    Flip,
    Flop,
    Rotate180,
    RotateLeft,
    RotateRight,
    Border,
    Nothing,
}

The 10 supported toilet-compatible filters (FR-003).

Each variant maps to a pure function on owned RenderGrids (AD-002). Names match toilet(1)’s -F chain vocabulary 1:1 (crop, gay, metal, flip, flop, rotate180, rotateleft, rotateright, border, plus the always-available nothing identity).

Variants

Crop

Trim surrounding all-blank rows and columns.

Gay

Per-column rainbow color sweep (the toilet --gay aesthetic).

Metal

Blue / gray metallic gradient.

Flip

Horizontal mirror (reverse each row’s columns).

Flop

Vertical mirror (reverse the order of rows).

Rotate180

Rotate 180° (combination of flip + flop).

RotateLeft

Rotate 90° counter-clockwise (transpose + flip).

RotateRight

Rotate 90° clockwise (transpose + flop).

Border

Draw a Unicode box-drawing border around the grid.

Nothing

No-op identity. Always available (no leaf gate).

Implementations

impl Filter

pub const fn name(&self) -> &'static str

Returns the canonical lowercase name parsed from a -F chain.

Trait Implementations

impl Clone for Filter

fn clone(&self) -> Filter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Filter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Filter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Filter

fn eq(&self, other: &Filter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
