Enum LockMode 

pub enum LockMode {
    Check,
    Virtual,
    WriteAsNeeded,
}

Lock-file update strategy for LockFlags::set_mode.

The three modes are mutually exclusive at the C-API level. Picking one writes into the underlying nix_flake_lock_flags slot, so chaining modes is meaningless. Exposing them as an enum makes that obvious at the call site.

Variants

Check

Require the lock file to be up-to-date; fail if it needs updating.

Virtual

Update the lock file in memory only; do not write it to disk.

WriteAsNeeded

Update and write the lock file to disk if it needs updating.

Trait Implementations

impl Clone for LockMode

fn clone(&self) -> LockMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LockMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LockMode

fn eq(&self, other: &LockMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
