Struct EnvStore 

pub struct EnvStore;

Reads secrets straight from process environment variables.

The service argument is ignored; account is interpreted as the env-var name. set / delete are deliberately unsupported: mutating process env from library code is unsafe in Rust 2024 and cross-thread-unsound on every platform.

Implementations

impl EnvStore

pub const fn new() -> Self

Construct a new env-backed store.

Trait Implementations

impl CredentialStore for EnvStore

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _service: &'life1 str, account: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<SecretString, CredentialError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Retrieve a secret by service/account. Returns CredentialError::NotFound when the store does not carry it.

fn set<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _: &'life1 str, _: &'life2 str, __arg3: SecretString, ) -> Pin<Box<dyn Future<Output = Result<(), CredentialError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store (or overwrite) a secret at service/account. Returns CredentialError::ReadOnly on stores that do not support mutation.

fn delete<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _: &'life1 str, _: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), CredentialError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Remove a secret. Missing entries are not an error. Returns CredentialError::ReadOnly on stores that do not support mutation.

impl Debug for EnvStore

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

Formats the value using the given formatter.

impl Default for EnvStore

fn default() -> EnvStore

Returns the “default value” for a type.
