Implementations

impl WorkBudget<'static>

pub const fn new(limit: usize) -> Self

Creates an independent local work slice.

impl<'a> WorkBudget<'a>

pub fn charge(&self) -> bool

Charges one work unit, returning false after exhaustion.

pub fn charge_by(&self, work: usize) -> bool

Charges several work units, with sticky exhaustion on refusal.

pub fn exhausted(&self) -> bool

Returns whether this slice has refused a charge.

pub fn exhaust(&self)

Marks this slice exhausted without consuming additional session work.

pub fn remaining(&self) -> usize

Returns unconsumed work units.

pub fn consumed(&self) -> usize

Returns work units consumed by successful charges.

pub fn child_slice(&self, limit: usize) -> WorkBudget<'static>

Creates an independent child slice capped by this budget’s remainder.

pub fn session_child_slice(&self, limit: usize) -> WorkBudget<'_>

Creates a child slice capped by this budget’s remainder and attached to its session.

pub fn consume_child(&self, child: &WorkBudget<'_>) -> bool
