Enum WsPolicy 

pub enum WsPolicy {
    None,
    SpaceRun,
    ZeroOrMore,
    OneOrMore,
    ExactSpace,
    Newline,
    Tab,
}

How a template literal run of whitespace matches input (§7.2).

Variants

None

The literal had no whitespace run in front of it, so no whitespace is consumed before matching it.

This variant is what lets SpaceRun mean what it says. Without it every literal would be tagged SpaceRun whether or not the template wrote a space run, the interpreter could not tell the two apart, and the only way to keep templates matching would be to implement SpaceRun as zero-or-more — contradicting its own definition.

SpaceRun

A run of ordinary spaces matches one or more spaces or tabs (the default, flexible rule for AoC column alignment, §7.2).

ZeroOrMore

\s* — zero or more spaces or tabs.

OneOrMore

\s+ — one or more spaces or tabs.

ExactSpace

\x20 — exactly one ASCII space.

Newline

\n — one line ending.

Tab

\t — one tab.
