Cargo Features

gix-features has no features set by default.

[dependencies]
gix-features = { version = "0.42.1", features = ["progress", "progress-unit-human-numbers", "progress-unit-bytes", "fs-read-dir", "tracing", "tracing-detail", "parallel", "once_cell", "walkdir", "io-pipe", "crc32", "zlib", "zlib-ng", "zlib-rs", "zlib-rust-backend", "cache-efficiency-debug", "document-features"] }

progress = prodash

Provide traits and utilities for providing progress information. These can then be rendered using facilities of the prodash crate.

Affects gix-features::progress…

progress-unit-human-numbers

Provide human-readable numbers as well as easier to read byte units for progress bars.

Enables unit-human of optional prodash

progress

Affects progress::count_with_decimals…

progress-unit-bytes

Provide human readable byte units for progress bars.

Enables bytesize, unit-bytes of optional prodash

Affects progress::bytes…

fs-read-dir

Provide utilities suitable for working with the std::fs::read_dir().

Enables gix-utils

tracing

Implement tracing with tracing-core, which provides applications with valuable performance details if they opt-in to it.

Note that this may have overhead as well, thus instrumentations should be used stategically, only providing coarse tracing by default and adding details only where needed while marking them with the appropriate level.

Enables tracing of gix-trace

tracing-detail

If enabled, detailed tracing is also emitted, which can greatly increase insights but at a cost.

Enables tracing-detail of gix-trace

parallel

Use scoped threads and channels to parallelize common workloads on multiple objects. If enabled, it is used everywhere where it makes sense. As caches are likely to be used and instantiated per thread, more memory will be used on top of the costs for threads. The threading module will contain thread-safe primitives for shared ownership and mutation, otherwise these will be their single threaded counterparts. This way, single-threaded applications don't have to pay for threaded primitives.

Enables crossbeam-channel and parking_lot

crossbeam-channel:

'parallel' feature

Affects parallel::optimize_chunk_size_and_thread_limit, parallel::num_threads, parallel::in_parallel_if…

once_cell

If enabled, OnceCell will be made available for interior mutability either in sync or unsync forms.

Enables once_cell

walkdir

Makes facilities of the walkdir crate partially available. In conjunction with the parallel feature, directory walking will be parallel instead behind a compatible interface.

Enables walkdir

used when parallel is off

and gix-path and gix-utils

gix-path:

for walkdir

Affects fs::walkdir…

io-pipe

• an in-memory unidirectional pipe using bytes as efficient transfer mechanism.

Enables bytes

pipe

Affects io::pipe, gix-features::io…

crc32

provide a proven and fast crc32 implementation.

Enables crc32fast

hashing

Affects hash::crc32_update, hash::crc32…

zlib zlib-ng? zlib-ng-compat? zlib-rs? zlib-rust-backend? zlib-stock?

Enable the usage of zlib-related utilities to compress or decompress data. This enables the flate2 crate, and always uses the high-performance zlib-rs backend. Note that the various past features for selecting zlib backends are now deprecated and do nothing.

Enables flate2 and thiserror

flate2:

zlib module

Affects gix-features::zlib…

zlib-ng = zlib

Deprecated: gix always uses zlib-rs.

zlib-rs = zlib

Deprecated: gix always uses zlib-rs now. As of zlib-rs 0.5.0 (used by flate2
1.1.1), this no longer exports C symbols # by default, so it doesn't
conflict with any other zlib library that might be loaded into the same address space.

zlib-ng-compat zlib-stock zlib-rust-backend = zlib

Deprecated: gix always uses zlib-rs.

cache-efficiency-debug

Other

Count cache hits and misses and print that debug information on drop. Caches implement this by default, which costs nothing unless this feature is enabled

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

prodash progress?

document-features implicit feature

Enables document-features

document-features:
