Struct SettingWarning 

pub struct SettingWarning {
    pub section: String,
    pub key: String,
    pub did_you_mean: Option<&'static str>,
}

Something in config.toml that was read and then ignored.

A warning rather than an error, deliberately: refusing an unknown key would mean an older binary could not read a config written for a newer one, which is a worse failure than a typo. But silence is worse than both — a misspelled w_vec changes no behaviour and says nothing, and the user is left believing they tuned something.

Fields

section: String

The TOML section it appeared in, without brackets. Empty for an unknown section, where Self::key is the section’s own name.

key: String

The key (or section) nobody claimed.

did_you_mean: Option<&'static str>

The closest known name, when one is close enough to be worth offering.
