Struct CredentialChain 

Source 
pub struct CredentialChain { /* private fields */ }
Expand description

Ordered credential sources, with one selected identity retained during refresh.

Sources return None when unavailable. Errors stop discovery. Concurrent callers share discovery and refresh, and a selected source is never replaced by another identity.

Implementations§

Source§

impl CredentialChain

Source

pub fn new(providers: Vec<TokenSource>) -> Self
