Cargo Features

[dependencies]
sigma-rust = { version = "0.3.0", default-features = false, features = ["serde_json"] }
default = serde_json

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

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.

serde_json default

Affects error::JSONError, sigma-rust::event_from_json, sigma-rust::events_from_json
