Enum KeyNaming 

#[non_exhaustive]
pub enum KeyNaming<'a> {
    Dotted(&'a str),
    Env(&'a str),
}

How problem messages name a setting, so they match how the operator wrote it.

• Dotted("mcp.oauth") names the issuer mcp.oauth.issuer — a key in a YAML (or other serde) config nested under that path.
• Env("MYAPP_OAUTH_") names it MYAPP_OAUTH_ISSUER — the field name uppercased and appended to the prefix.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Dotted(&'a str)

A dotted path prefix; a field is named <prefix>.<field>.

Env(&'a str)

An environment-variable prefix; a field is named <PREFIX><FIELD>.

Implementations

impl KeyNaming<'_>

pub fn key(&self, field: &str) -> String

The name of setting field (a lower-case OAuthConfig field name).

pub fn section(&self) -> String

The name of the whole block: the dotted prefix itself, or PREFIX* for environment variables. An empty dotted prefix (the OAuth fields at the root of the config) has no path to name, so the block is called OAuth config rather than rendering as an empty string.

pub fn to_buf(&self) -> KeyNamingBuf

The owned form, for storing past the borrow.
