Trait Implementations

impl Debug for FileStoreError

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

Formats the value using the given formatter.

impl Display for FileStoreError

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

Formats the value using the given formatter.

impl Error for FileStoreError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for FileStoreError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<VfsError> for FileStoreError

fn from(source: VfsError) -> Self

Converts to this type from the input type.

impl KVStore<FileStoreError> for FsKvStore

fn create_bucket(&mut self, key: &[u8]) -> Result<(), FileStoreError>

creates a new bucket

fn delete_record(&mut self, key: &[u8]) -> Result<(), FileStoreError>

delete a data record (could also be a bucket)

fn store_record( &mut self, key: &[u8], value: &[u8], ) -> Result<(), FileStoreError>

store a data record

fn fetch_record(&self, key: &[u8]) -> Result<Vec<u8>, FileStoreError>

fetch a data record

fn list_records( &self, from: &[u8], to: &[u8], ) -> Result<Vec<Vec<u8>>, FileStoreError>

list all records in between from and to

fn exists(&self, key: &[u8]) -> Result<bool, FileStoreError>

check if an entry exists in the database
