Cargo Features

[dependencies]
toml = { version = "0.9.11+spec-1.1.0", default-features = false, features = ["std", "serde", "parse", "display", "fast_hash", "debug", "unbounded", "preserve_order"] }
default = display, parse, serde, std

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

std default debug? preserve_order?

Enables std of optional indexmap, optional serde_core, serde_spanned, toml_datetime, optional toml_parser, and optional toml_writer

serde_core:

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

serde default

Enables serde_core, serde of serde_spanned and toml_datetime

Affects toml::value, toml::ser, toml::macros, de::from_str, de::from_slice

parse default

Enables toml_parser and winnow

Affects de::from_str, de::from_slice

display default

Enables toml_writer

Affects ser::to_string, ser::to_string_pretty

fast_hash = preserve_order

Enables foldhash

debug = std

Enables anstream and anstyle, debug of optional toml_parser

unbounded

Provide a method disable_recursion_limit to parse arbitrarily deep structures without any consideration for overflowing the stack. Additionally you will need to be careful around other recursive operations on the parsed result which may overflow the stack after deserialization has completed, including,
but not limited to, Display and Debug and Drop impls.

preserve_order fast_hash? = std

Use indexmap rather than BTreeMap as the map type of toml::Value.
This allows data to be read into a Value and written back to a TOML string while preserving the order of map keys in the input.

Enables indexmap
