Struct CacheRetentionLimits 

pub struct CacheRetentionLimits { /* private fields */ }

Caller-selected age and logical-size thresholds for cache maintenance.

Thresholds do not select a cleanup algorithm or schedule maintenance. Exact-entry pruning removes expired and then least-recently-used entries, skipping live retained records. Shared-target maintenance clears the entire mutable Cargo state when either threshold is exceeded. It preserves only the target root and IC Build’s coordination metadata; do not colocate unrelated data there. Without thresholds, no committed entry or shared compiler state is removed. Explicit transaction maintenance may still clear abandoned staging.

Implementations

impl CacheRetentionLimits

pub const fn new() -> Self

pub const fn max_age(self) -> Option<Duration>

Configured maximum entry age, if any.

pub const fn max_size_bytes(self) -> Option<u64>

Configured maximum logical cache size in bytes, if any.
