Cargo Features

[dependencies]
mongodb = { version = "2.7.1", default-features = false, features = ["tokio-runtime", "async-std-runtime", "sync", "tokio-sync", "openssl-tls", "bson-chrono-0_4", "bson-serde_with", "bson-uuid-0_8", "bson-uuid-1", "aws-auth", "azure-kms", "gcp-kms", "zstd-compression", "zlib-compression", "snappy-compression", "in-use-encryption-unstable", "tracing-unstable"] }

NOTE: any new features added to this list should also be added to the features list in the [package.metadata.docs.rs] section below.

default = tokio-runtime: The tokio-runtime feature is set by default whenever mongodb is added without default-features = false somewhere in the dependency tree.
tokio-runtime default tokio-sync? = serde_bytes: Enables macros, net, process, rt and time of tokio
async-std-runtime sync? = async-executor, async-std, async-std-resolver: Enables attributes and unstable of async-std, compat of tokio-util
sync = async-std-runtime: Affects mongodb::sync…
tokio-sync = tokio-runtime: Affects mongodb::sync…
openssl-tls = openssl, openssl-probe, tokio-openssl: Affects options::TlsOptions.allow_invalid_hostnames…
bson-chrono-0_4: Enable support for v0.4 of the chrono crate in the public API of the BSON library.

Enables chrono-0_4 of bson
bson-serde_with: Enable support for the serde_with crate in the BSON library.

Enables serde_with of bson
bson-uuid-0_8: Enable support for v0.8 of the uuid crate in the public API of the BSON library.

Enables uuid-0_8 of bson
bson-uuid-1: Enable support for v1.x of the uuid crate in the public API of the BSON library.

Enables uuid-1 of bson

This can only be used with the tokio-runtime feature flag.
azure-kms = reqwest: Enable support for on-demand Azure KMS credentials.
This can only be used with the tokio-runtime feature flag.
gcp-kms = reqwest: Enable support for on-demand GCP KMS credentials.
This can only be used with the tokio-runtime feature flag.

zlib-compression = flate2
snappy-compression = snap
in-use-encryption-unstable = mongocrypt, num_cpus, rayon: Enables support for client-side field level encryption and queryable encryption.
The In Use Encryption API is unstable and may have backwards-incompatible changes in minor version updates.

Affects options::DropCollectionOptions.encrypted_fields, options::CreateCollectionOptions.encrypted_fields…
tracing-unstable = log, tracing: Enables support for emitting tracing events. The tracing API is unstable and may have backwards-incompatible changes in minor version updates. TODO: pending https://github.com/tokio-rs/tracing/issues/2036 stop depending directly on log.

Affects options::ClientOptions.tracing_max_document_length_bytes…
