match_cond

cond

return expression associated with the condition. If <code>cond</code> is matched with <code>x</code>, then <code>do</code>
should be evaluated and returned in a list with <code>TRUE</code>: <code>list(TRUE, eval(do))</code>.

Called by <code><a rd-options="" href="/link/Match?package=matchr&version=0.1.0" data-mini-rdoc="matchr::Match">Match</a></code> the check whether a condition matches. Used to create custom methods for matching.

Inspired by pattern matching and enum types in Rust
and many functional programming languages, this package offers
an updated version of the 'switch' function called 'Match' that
accepts atomic values, functions, expressions, and enum variants.
Conditions and return expressions are separated by '->' and
multiple conditions can be associated with the same return expression
using '|'. 'Match' also includes support for 'fallthrough'. The
package also replicates the Result and Option enums from Rust.
