Struct WindowOpts 

pub struct WindowOpts {
    pub tool_head: usize,
    pub tool_tail: usize,
    pub per_msg_chars: usize,
    pub budget_chars: Option<usize>,
    pub tool_byte_cap: usize,
}

Fields

tool_head: usize

Lines kept at the head of a folded tool result.

tool_tail: usize

Lines kept at the tail of a folded tool result.

per_msg_chars: usize

Char cap for a single user/assistant message (head+tail beyond it).

budget_chars: Option<usize>

Total char budget across the rendered turns; None folds the whole session. When set, the most RECENT turns are kept (walk from the end).

tool_byte_cap: usize

Byte cap for a single folded tool result. Line folding alone can’t bound a result that is one enormous line, so the folded text is additionally clipped to this many bytes (on a char boundary).

impl Default for WindowOpts

fn default() -> Self

Returns the “default value” for a type.
