Enum PatternElement 

pub enum PatternElement {
    Wildcard,
    Skip,
    Exclude,
    Exact(i32),
    DirectionExclusive(Direction),
    DirectionInclusive(Direction),
    Offset(i32),
    Range(i32, i32),
}

Pattern element types for specifying connectivity rules per axis.

Variants

Wildcard

"*" - matches any coordinate on this axis

Skip

"?" - pass through source coordinate (dst = src)

Exclude

"!" - exclude source coordinate (all except src)

Exact(i32)

Absolute coordinate value

DirectionExclusive(Direction)

"?+" or "?-" - all coordinates strictly above/below src

DirectionInclusive(Direction)

"?+=" or "?-=" - all coordinates at or above/below src

Offset(i32)

"?+N" or "?-N" - single coordinate offset from src

Range(i32, i32)

"?-A:?+B" - inclusive range [src + lo, src + hi]
