Cargo Features

[dependencies]
sgp4 = { version = "2.1.0", default-features = false, features = ["std", "alloc", "serde", "libm"] }

default = alloc, serde, std

These default features are set whenever sgp4 is added without default-features = false somewhere in the dependency tree.

std default = alloc

Enables std of anyhow, chrono, optional serde, and optional serde_json

serde:

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

alloc default serde std = anyhow

Affects tle::Elements.object_name, tle::Elements.international_designator, tle::parse_2les, tle::parse_3les…

serde default = alloc

Enables serde of chrono, alloc and derive of serde and alloc of serde_json

serde_json:

Provide integration for heap-allocated collections without depending on the rest of the Rust standard library. NOTE: Disabling both std and alloc features is not supported yet.

libm

Enables libm of num-traits

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.
