TWiR quote of the week

[crumplecup]

I find this sentiment well-stated and apropos, suitable for quotation in whole or in part:

@khimru

while people often argue about “Rust way” of doing things (whether it's explicit or not, etc)… the actual rule that Rust development follows is: Rust doesn't believe in magic.

I think that's the simplest formulation of all-encompassing principle: no magic at runtime. It's as simple as that.

Rust have tons of magic. Type inference, lifetime calculations, tricky HRBT rules and so on.

But under all that… the guiding idea of Rust is: magic is fallible and thus it must only be used in compile time.

I'm not sure if anyone ever planned to make Rust an anti-magical language, but that's how it works today: most constructs which are rejected are rejected “because they are not explicit enough”, but in reality they are rejected because they add potentially fallible, hidden, runtime magic to Rust.
