Struct FetchContext 

#[non_exhaustive]
pub struct FetchContext {
    pub key_name: String,
}

Information given to a KeyFetch implementation when it is asked to produce a key.

The struct is #[non_exhaustive] — additional fields (a tracing span, a caller identifier, telemetry hooks) will be added in later phases without requiring a major version bump.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key_name: String

Logical name of the key being requested.

Fetchers that talk to a named store (keychain entries, environment variables, file paths) use this to disambiguate which key to load. It does not carry any policy meaning to the vault itself.

Implementations
