Implementations

impl Credentials

pub fn api_key(key: impl Into<String>) -> Self

Creates API key credentials

pub fn access_key( access_key: impl Into<String>, secret_key: impl Into<String>, ) -> Self

Creates access key credentials

pub fn access_key_with_session( access_key: impl Into<String>, secret_key: impl Into<String>, session_token: impl Into<String>, ) -> Self

Creates access key credentials with session token

pub fn oauth2(access_token: impl Into<String>) -> Self

Creates OAuth 2.0 credentials

pub fn oauth2_with_refresh( access_token: impl Into<String>, refresh_token: impl Into<String>, ) -> Self

Creates OAuth 2.0 credentials with refresh token

pub fn service_account_from_json(json: impl Into<String>) -> Result<Self>

Creates service account credentials from JSON

pub fn service_account_from_file(path: impl AsRef<Path>) -> Result<Self>

Creates service account credentials from file

pub fn sas_token(token: impl Into<String>) -> Self

Creates SAS token credentials

pub fn iam_role( role_arn: impl Into<String>, session_name: impl Into<String>, ) -> Self

Creates IAM role credentials

pub fn is_expired(&self) -> bool

Checks if credentials are expired

pub fn needs_refresh(&self) -> bool

Returns true if credentials need refresh

pub fn variant_name(&self) -> &'static str

Returns a short, secret-free name for the credentials variant.

Intended for diagnostics/error messages where the full Debug representation would risk leaking secret material (access keys, tokens, service account JSON, etc.).

Trait Implementations

impl Clone for Credentials

fn clone(&self) -> Credentials

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Credentials

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

Formats the value using the given formatter.
