Token budget allocation.

§system_prompt: usize§user_model: usize§conversation_history: usize§response_buffer: usize§attachments: usizeCap on rendered path-attachments (snapshots of files/dirs the user referenced in chat). Truncated to fit by the assembler.
total_context: usizeImplementations§
Source§impl TokenBudget
impl TokenBudget
Sourcepub fn memory_budget(&self) -> usize
pub fn memory_budget(&self) -> usize
Calculate remaining budget for memories.
Sourcepub fn for_context_size(total_tokens: usize) -> Self
pub fn for_context_size(total_tokens: usize) -> Self
Build a budget scaled to a model’s real context window.
Fixed overheads (system prompt, user-model snapshot, response buffer) don’t grow with the window, so they’re reserved as constants. The remaining working pool is split proportionally between conversation history, path-attachments, and retrieved memories — so a 128k-window model reads far more file content and recalls more memory than the conservative 8k default, instead of clipping everything to a fixed cap.
At total_tokens == 8192 this stays close to the historical fixed
split (history ≈2k, attachments ≈2.5k, memory ≈2.5k). Memory is the
implicit remainder via Self::memory_budget.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
