# Miri flags
#
# -Zmiri-disable-isolation
# We need to pass the miri flag to disable host isolation in order to access host for clock information on timestamps
# more information can be found: https://github.com/rust-lang/miri#miri--z-flags-and-environment-variables
#
# -Zmiri-tree-borrows
# Miri's default aliasing model (stacked borrows) is known to be unnecessarily restrictive. Their alternative
# aliasing model (tree borrows) accepts valid programs that stacked borrows would reject.
# For more information, see: https://www.ralfj.de/blog/2023/06/02/tree-borrows.html
