Trait CredentialsProvider 

pub trait CredentialsProvider:
    Debug
    + Send
    + Sync {
    // Required methods
    fn credentials_async(
        &self,
    ) -> Pin<Box<dyn Future<Output = Result<CredentialsSnapshot>> + Send + '_>>;
    fn credentials_blocking(&self) -> Result<CredentialsSnapshot>;
}

Source of credential snapshots for request signing.

Implement this trait when credentials may rotate over time. If the underlying provider performs network calls or expensive refreshes, wrap it in crate::CachedProvider so multiple requests can share cached credentials and coalesce refresh work.

Required Methods

fn credentials_async( &self, ) -> Pin<Box<dyn Future<Output = Result<CredentialsSnapshot>> + Send + '_>>

Available on crate feature async only.

Returns credentials asynchronously.

fn credentials_blocking(&self) -> Result<CredentialsSnapshot>

Available on crate feature blocking only.

Returns credentials in blocking mode.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
