Cargo Features

[dependencies]
axum-jrpc = { version = "0.7.0", default-features = false, features = ["anyhow_error", "simd", "serde_json"] }
default = serde_json

The serde_json feature is set by default whenever axum-jrpc is added without default-features = false somewhere in the dependency tree.

anyhow_error = anyhow
simd = simd-json
serde_json default

Enables serde_json

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.

anyhow anyhow_error?
simd-json simd?
