Struct OutputLimitConfig 

pub struct OutputLimitConfig { /* private fields */ }

Configurable output size limit.

Threaded through KernelConfig → ExecContext → kernel pipeline execution. Runtime-mutable via the kaish-output-limit builtin.

Implementations

impl OutputLimitConfig

pub fn none() -> Self

No limiting — REPL/embedded/test default.

pub fn default_limit() -> usize

Default limit used by on subcommand and set -o output-limit.

pub fn mcp() -> Self

MCP-safe defaults: 8KB limit, 1KB head, 512B tail, disk spill.

pub fn in_memory(self) -> Self

Switch to in-memory truncation — no disk spill, no host filesystem writes. For runtime read-only kernels (e.g. kaibo). Builder form of set_spill_mode.

Note: a NoLocal VFS mount forces this mode automatically at kernel construction, so an embedder only needs this for a localfs-mounted kernel it nonetheless wants to keep off the host disk.

pub fn is_enabled(&self) -> bool

Whether output limiting is enabled.

pub fn spill_mode(&self) -> SpillMode

The spill mode (disk vs in-memory truncation).

pub fn set_spill_mode(&mut self, mode: SpillMode)

Set the spill mode.

pub fn max_bytes(&self) -> Option<usize>

The maximum output size in bytes, if set.

pub fn head_bytes(&self) -> usize

Bytes of output head to preserve in truncated result.

pub fn tail_bytes(&self) -> usize

Bytes of output tail to preserve in truncated result.

pub fn set_limit(&mut self, max: Option<usize>)

Set the output limit. None disables limiting.

pub fn set_head_bytes(&mut self, bytes: usize)

Set the head preview size.

pub fn set_tail_bytes(&mut self, bytes: usize)

Set the tail preview size.
