Struct CacheBudget 

pub struct CacheBudget {
    pub max_bytes: u64,
    pub used_bytes: u64,
}

Bounded cache budget for incremental causal state.

Fields

max_bytes: u64

Maximum retained cache bytes.

used_bytes: u64

Bytes currently retained (updated by the state crate).

Implementations

impl CacheBudget

pub const fn new(max_bytes: u64) -> Self

Fresh budget with max_bytes capacity and zero usage.

pub const fn unlimited() -> Self

Unlimited soft budget (still subject to OS limits).

pub const fn remaining(self) -> u64

Remaining capacity in bytes.

pub const fn can_admit(self, additional: u64) -> bool

Whether additional bytes would fit under the budget.
