Cargo Features

[dependencies]
uhg-custom-appollo-roouter = { version = "1.31.1", default-features = false, features = ["global-allocator", "dhat-heap", "dhat-ad-hoc", "failfast", "console", "docs_rs"] }

default = global-allocator

The global-allocator feature is set by default whenever uhg-custom-appollo-roouter is added without default-features = false somewhere in the dependency tree.

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"

Enables tracing of tokio

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 =0.5.5

note: this dependency should always be pinned, prefix the version with an =

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.
