Struct FileStorage 

pub struct FileStorage;

Unencrypted file-based credential storage.

Stores each credential as JSON at <config-base>/<app>/credentials/<provider>-<env>.json, where <app> is the key’s app_id (or provider when app_id is empty) and <config-base> is resolved by config_base_dir. On Unix the file is created 0600 and the parent directory is best-effort restricted to 0700.

Credentials are written in clear text, so prefer the system keychain where one is available.

Implementations

impl FileStorage

pub fn new() -> Self

Creates a file-storage backend.

Trait Implementations

impl Clone for FileStorage

fn clone(&self) -> FileStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FileStorage

impl CredentialStorage for FileStorage

fn load<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 CredentialKey<'life2>, ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>

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

Loads the stored blob for key, or None when absent or unreadable.

fn save<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, key: &'life1 CredentialKey<'life2>, value: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Persists value for key, replacing any existing value.

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

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

Removes the blob for key. Best-effort: absence is not an error.

fn list<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Lists environment names with stored credentials, if the backend supports enumeration. The default returns an empty list (the keychain cannot be enumerated by service prefix).

impl Debug for FileStorage

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

Formats the value using the given formatter.

impl Default for FileStorage

fn default() -> FileStorage

Returns the “default value” for a type.
