Cargo Features

[dependencies]
mail-parser = { version = "0.9.3", default-features = false, features = ["full_encoding", "serde_support", "ludicrous_mode"] }
default = full_encoding

The full_encoding feature is set by default whenever mail-parser is added without default-features = false somewhere in the dependency tree.

full_encoding default = encoding_rs
serde_support = serde
ludicrous_mode

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.

encoding_rs full_encoding
serde serde_support?
