cicd jobs failing

[AzothZephyr]

gm,

i see this repos cicd jobs are failing. i took a look and this is because the version of rust used in the cicd pipeline is pegged at the nightly tool chain from 2022-04-25. it fails because the hashbrown dependency requires rustc version 1.64.0 or newer.

i'm happy to fix test and propose pr to fix but would like to know what version of rust the team would like me to set it to.

thx,
