[dependencies]
serde-json-core = { version = "0.6.0", default-features = false, features = ["std", "custom-error-messages", "defmt"] }

serde:

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

custom-error-messages = heapless

defmt

Enables defmt and defmt-03 of optional heapless

heapless:

Implement defmt::Format from defmt v0.3
