Struct CommandLog 

pub struct CommandLog { /* private fields */ }

Bounded FIFO ring of CommandLogEntry. Pure state — no global, no I/O — so its push/evict/snapshot contract is unit-testable in isolation.

Implementations

impl CommandLog

pub fn new() -> Self

An empty log.

pub fn push(&mut self, entry: CommandLogEntry)

Append entry, evicting the oldest when the ring is already at MAX_ENTRIES.

pub fn len(&self) -> usize

Number of retained entries.

pub fn is_empty(&self) -> bool

true when nothing has been logged yet.

pub fn iter(&self) -> impl Iterator<Item = &CommandLogEntry>

Oldest-first iterator over the retained entries.

pub fn snapshot(&self) -> Vec<CommandLogEntry>

Owned, oldest-first clone of the retained entries — the boundary the TUI copies across so it never renders off the live global.

pub fn clear(&mut self)

Drop every entry.
