Crate mbx_cache_store 

Store inspection and garbage collection.

The store holds six trees: cas/v1 for content-addressed objects, action-results/v1 for the results that reference them, task-manifests/v1 for the prediction index, checkouts/v1 for the checkouts that have built each identity, build-receipts/v1 for exact completed build closures, and sessions/v1 for per-build event streams. Only the first two are collected for size; manifests and receipts are small, checkout records expire with their checkout claims, and session streams are bounded by age and count because they are history rather than cache content.

WorkspaceTarget

One Cargo workspace and the target directory recorded for its build.

Enums

ExportForm

How an export is laid out on disk.

Functions

checkout_is_live

Whether a checkout is still on disk, corroborating absence through its immediate parent.

checkout_is_live_on

Whether the checkout a record names is still on disk.

checkout_workspace_target

Return the target directory recorded for this checkout’s latest build.

claim_sweep

Claim a due sweep before doing work, including interrupted attempts.

export_checkout

Export the complete local cache closure of this checkout’s most recent build.

export_checkout_as

Export one checkout’s closure in the requested form.

export_checkout_with

Export one checkout’s closure together with higher-level CAS attachments.

export_group

Export the union of every completed build recorded under one CI group.

export_group_as

Export a grouped closure in the requested form.

export_group_with

Export a grouped closure together with higher-level CAS attachments.

gc

Evict objects until the store fits within max_bytes.

gc_dry_run

Describe the collection gc would perform without changing the store.

gc_dry_run_after_stale

Describe what gc_stale_compilers followed by gc_dry_run would remove, counting nothing twice and measuring the budget after the stale pass.

gc_stale_compilers

Drop cached compilations for Rust compiler versions that have gone unused.

group_workspace_targets

Return every Cargo target represented by the pending receipts in a group.

import_archive

Validate a cache export in isolation, then publish its objects and actions.

import_archive_with_attachments

Import a cache archive and return its named higher-level CAS roots.

largest

Return the largest blobs and action-result records in descending order.

live_project_cache_bytes

The reusable cache bytes of each live workspace, as projects counts them.

projects

Attribute cache and target bytes to each recorded workspace.

record_build_receipt

Record an exact completed build for checkout and grouped exports.

record_checkout

Record that workspace_root built identity.

record_sweep

Record a finished sweep at the current time.

remove_project

Remove checkout claims belonging to exactly one workspace.

same_filesystem_paths

Whether two existing paths sit on the same filesystem, so a rename can carry a directory from one to the other.

stats

Summarize what the store currently holds.

sweep_if_due

Sweep the store if interval has passed since the last attempt.

sweep_is_due

Whether the interval since the last recorded sweep has passed.

verify

Verify every addressable CAS object and action-result record.
