pub struct PredicateCeiling {
pub require_approval_threshold: usize,
pub block_threshold: usize,
pub approver: Approver,
}Expand description
Predicate-count explosion limits applied to a slice’s resolved predicate union before evaluation begins.
Cross-directory union semantics make it cheap to accidentally pull a pathological number of predicates into one slice — touch ten leaf directories that each declare a dozen sibling-specific invariants and suddenly Ship Captain is paying serial wall-clock for every one of them. The ceiling makes that cost visible:
- Below
require_approval_thresholdevaluation proceeds without ceremony. - Between
require_approval_thresholdandblock_thresholdthe slice still ships, but only after a named approver co-signs (RequireApproval). - At or above
block_thresholdFlow refuses to evaluate the union and returnsBlockso a human can split the slice or prune predicates.
Fields§

Implementations§
Source§impl PredicateCeiling
impl PredicateCeiling
Sourcepub const DEFAULT_REQUIRE_APPROVAL_THRESHOLD: usize = 256
pub const DEFAULT_REQUIRE_APPROVAL_THRESHOLD: usize = 256
Default soft ceiling. Slices with this many predicates are large enough to warrant a human glance even when every predicate passes.
Sourcepub const DEFAULT_BLOCK_THRESHOLD: usize = 1024
pub const DEFAULT_BLOCK_THRESHOLD: usize = 1024
Default hard ceiling. Beyond this the union is almost always a
misconfigured invariants.harn tree, not a legitimate slice.
Sourcepub const DEFAULT_APPROVER_ROLE: &'static str = "flow-platform"
pub const DEFAULT_APPROVER_ROLE: &'static str = "flow-platform"
Default approver role for soft-ceiling escalations.

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().

painted.white();Source§fn bright_black(&self) -> 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().

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().

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);
