Trait Implementations

impl Default for NativeFilestore

fn default() -> NativeFilestore

Returns the “default value” for a type.

impl VirtualFilestore for NativeFilestore

fn create_file(&self, file_path: &str) -> Result<(), FilestoreError>

fn remove_file(&self, file_path: &str) -> Result<(), FilestoreError>

fn file_name<'a>( &self, full_path: &'a str, ) -> Result<Option<&'a str>, FilestoreError>

Extract the file name part of a full path.

fn truncate_file(&self, file_path: &str) -> Result<(), FilestoreError>

Truncating a file means deleting all its data so the resulting file is empty. This can be more efficient than removing and re-creating a file.

fn create_dir(&self, dir_path: &str) -> Result<(), FilestoreError>

fn remove_dir(&self, dir_path: &str, all: bool) -> Result<(), FilestoreError>

fn read_data( &self, file_name: &str, offset: u64, read_len: u64, buf: &mut [u8], ) -> Result<(), FilestoreError>

fn write_data( &self, file: &str, offset: u64, buf: &[u8], ) -> Result<(), FilestoreError>

fn is_file(&self, str_path: &str) -> Result<bool, FilestoreError>

fn exists(&self, path: &str) -> Result<bool, FilestoreError>

fn file_size(&self, str_path: &str) -> Result<u64, FilestoreError>

fn calculate_checksum( &self, file_path: &str, checksum_type: ChecksumType, size_to_verify: u64, verification_buf: &mut [u8], ) -> Result<u32, FilestoreError>

This special function is the CFDP specific abstraction to calculate the checksum of a file. This allows to keep OS specific details like reading the whole file in the most efficient manner inside the file system abstraction.

fn filename_from_full_path(path: &str) -> Option<&str>

where Self: Sized,

fn is_dir(&self, path: &str) -> Result<bool, FilestoreError>

fn checksum_verify( &self, expected_checksum: u32, file_path: &str, checksum_type: ChecksumType, size_to_verify: u64, verification_buf: &mut [u8], ) -> Result<bool, FilestoreError>

This special function is the CFDP specific abstraction to verify the checksum of a file. This allows to keep OS specific details like reading the whole file in the most efficient manner inside the file system abstraction.
