SearchBudget

Struct SearchBudget 

Source
pub struct SearchBudget {
    pub max_expansions: Option<usize>,
    pub max_duration: Option<Duration>,
}
Expand description

Caller-chosen expansion and/or wall-clock limits for one search.

Both fields are independent optional caps. Default / Self::UNLIMITED means the solver runs until found, no-path, or an owner-defined hard stop.

Fields§

§max_expansions: Option<usize>

Maximum algorithm-defined expansions (see lane visited_nodes docs).

When set, the solver may expand at most this many nodes. Finding the goal on the last allowed expansion still returns found.

§max_duration: Option<Duration>

Maximum wall-clock duration measured from search start (BudgetWatch::start).

Implementations§

Source§

impl SearchBudget

Source

pub const UNLIMITED: SearchBudget

No expansion or wall-clock limit.

Source

pub const fn max_expansions(limit: usize) -> SearchBudget

Expansion-only budget.

Source

pub const fn max_duration(limit: Duration) -> SearchBudget

Wall-clock-only budget.

Source

pub const fn with_max_expansions(self, limit: usize) -> SearchBudget

Sets Self::max_expansions, preserving any duration limit.

Source

pub const fn with_max_duration(self, limit: Duration) -> SearchBudget

Sets Self::max_duration, preserving any expansion limit.

Source

pub const fn is_unlimited(&self) -> bool

Whether both caps are unset.
