About Disk Usage Analyzer

dua (→ Disk Usage Analyzer) is a tool to conveniently learn about the usage of disk space of a given directory. It's parallel by default and will max out your SSD, providing relevant information as fast as possible. Optionally delete superfluous data, and do so more quickly than rm.

What's new in 2.46.0

A bugfix release, and one that should also restore cargo installations, making them function.
New Features
- make walk result buffering configurable per worker
Replace the fixed QUEUED_BATCHES_PER_WORKER constant with
Options::queued_batches_per_worker and a chainable builder method. Use
two queued batches per worker by default in both production and tests,
preserving the original bounded buffering behavior.
Consumers that pause to process entries can opt into a larger queue to
keep traversal workers busy, trading memory for less idle time. A value
of zero selects an unbuffered channel. Check the worker-count
multiplication so excessive capacities cannot silently overflow.
Update existing Options literals to inherit the new default. Verify the
actual queue capacity with one and two workers, and exercise larger and
unbuffered queues through the public single-root and multi-root walkers.

Bug Fixes
- pass strict workspace Clippy on Rust 1.99
Replace empty-container assertions with equality comparisons and empty
string checks with inequality comparisons. This satisfies Clippy's
assert_is_empty lint while showing actual values when assertions fail.
Locally allow the deprecated fetch_update alias in directory identifier
allocation. Its replacement, try_update, requires Rust 1.95, while
dua-core supports Rust 1.88. Preserve the existing atomic update and
overflow handling without raising the minimum supported Rust version.
- preserve flame graphs when export fails
