The mixed `number | bigint` representation was useful optimization for pointers. Now, pointers are represented as V8 externals. As part of the FFI stabilization effort we want to make `bigint` the only representation for `u64` and `i64`. BigInt representation performance is almost on par with mixed representation with the added benefit that its less confusing and users don't need manual checks and conversions for doing operations on the value. ``` cpu: AMD Ryzen 5 7530U with Radeon Graphics runtime: deno 1.43.6+92a8d09 (x86_64-unknown-linux-gnu) file:///home/divy/gh/ffi/main.ts benchmark time (avg) iter/s (min … max) p75 p99 p995 -------------------------------------------------------------------------- ----------------------------- nop 4.01 ns/iter 249,533,690.5 (3.97 ns … 10.8 ns) 3.97 ns 4.36 ns 9.03 ns ret bigint 7.74 ns/iter 129,127,186.8 (7.72 ns … 10.46 ns) 7.72 ns 8.11 ns 8.82 ns ret i32 7.81 ns/iter 128,087,100.5 (7.77 ns … 12.72 ns) 7.78 ns 8.57 ns 9.75 ns ret bigint (add op) 15.02 ns/iter 66,588,253.2 (14.64 ns … 24.99 ns) 14.76 ns 19.13 ns 19.44 ns ret i32 (add op) 12.02 ns/iter 83,209,131.8 (11.95 ns … 18.18 ns) 11.98 ns 13.11 ns 14.5 ns ``` |

Deno CLI Crate
This provides the actual deno executable and the user-facing APIs.
The deno crate uses the deno_core to provide the executable.
