[dependencies]
apollo-router = { version = "1.46.0-rc.0", default-features = false, features = ["global-allocator", "dhat-heap", "dhat-ad-hoc", "failfast", "console", "docs_rs", "telemetry_next"] }
- default = global-allocator
-
The
global-allocator
feature is set by default wheneverapollo-router
is added without
somewhere in the dependency tree.default-features = false - global-allocator default
-
Set the Rust global allocator on some platforms https://doc.rust-lang.org/std/alloc/index.html#the-global_allocator-attribute Enabled by default. Disable default features in library crates or to set it yourself:
[dependencies] apollo-router = {version = "1.20", default-features = false}
- dhat-heap = dhat
-
if you are doing heap profiling
- dhat-ad-hoc = dhat
- failfast
-
Prevents the query execution to continue if any error occurs while fetching the data of a subgraph. This is useful in development as you want to be alerted early when something is wrong instead of receiving an invalid result.
- console = console-subscriber
-
Enables usage of tokio-console with the router
tokio-console also requires at build time the environment variable RUSTFLAGS="--cfg tokio_unstable" - docs_rs
-
"fake" feature to disable V8 usage when building on docs.rs See https://github.com/apollographql/federation-rs/pull/185
Enables docs_rs of router-bridge
note: this dependency should always be pinned, prefix the version with an
=
- telemetry_next
-
Enables the use of new telemetry features that are under development and not yet ready for production use.
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.
