Enum SpillMode 

pub enum SpillMode {
    Disk,
    Memory,
}

Where overflow output goes when it exceeds the limit.

This is a runtime choice, distinct from the compile-time localfs feature: a localfs-built kernel can still be told to truncate in memory. A build without localfs always behaves as SpillMode::Memory regardless of this setting, since disk I/O is unavailable.

Variants

Disk

Write overflow to a disk spill file under paths::spill_dir() and keep a head+tail preview in the result (the message carries the file path). Requires the localfs feature. This is the default.

Auto-overridden to Memory at kernel construction when the VFS mount is NoLocal (memory-only) — such a kernel has no host filesystem to spill to. See Kernel::assemble.

Memory

Truncate in memory to head+tail only — no disk I/O, no recoverable file. For runtime read-only kernels (e.g. kaibo) that must never touch the host filesystem even when localfs is compiled in.

Trait Implementations

impl Clone for SpillMode

fn clone(&self) -> SpillMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SpillMode

impl Debug for SpillMode

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

Formats the value using the given formatter.

impl Default for SpillMode

fn default() -> SpillMode

Returns the “default value” for a type.

impl Eq for SpillMode

impl PartialEq for SpillMode

fn eq(&self, other: &SpillMode) -> 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.
