Struct CredentialChain 

pub struct CredentialChain { /* private fields */ }

An ordered chain of credential resolvers for a single provider.

Resolvers are tried in priority order (lowest first). The first resolver that returns Some(credential) wins.

Implementations

impl CredentialChain

pub fn new( provider_name: &'static str, resolvers: Vec<Box<dyn CredentialResolver>>, ) -> Self

Build a chain for the given provider. Resolvers are sorted by priority.

pub fn empty(provider_name: &'static str) -> Self

Build an empty chain (always returns NoCredentials).

pub fn resolve(&self) -> Result<ResolvedCredential, CredentialError>

Resolve credentials by walking the chain in priority order.

pub fn status(&self) -> Vec<CredentialStatus>

Return status of each resolver in the chain.

pub fn login_sources(&self) -> Vec<&dyn CredentialResolver>

Return resolvers that support interactive login.

pub fn get_resolver(&self, id: &str) -> Option<&dyn CredentialResolver>

Find a resolver by id.

pub fn resolver_ids(&self) -> impl Iterator<Item = &str>

Iterate over all resolver IDs in priority order.

pub fn provider_name(&self) -> &str

Provider name this chain serves.

pub fn len(&self) -> usize

Number of resolvers in the chain.

pub fn is_empty(&self) -> bool

Whether the chain has no resolvers.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
