Implementations

impl FileSystem

pub fn init() -> FileSystem

Name

init

Purpose

Initialises a SSVMContainer file system object

Input

N/A

Returns

FileSystem object

Example

let fs = ssvm_container::storage::file_system::FileSystem::init();

pub fn create_application(&self, _bytecode_wasm: &str) -> String

Name

create_application

Purpose

Store Wasm on the file system so that it’s funtions can be executed later

Input

An instance of the FileSystem object A complete .wasm file in string format

Returns

A unique identifier which can be used to access the application later

Example

let bytecode_wasm = String::from(“0x1234567890”); let uuid = ssvm_container::storage::file_system::FileSystem::create_application(&fs, &bytecode_wasm);

pub fn read_application(&self, _application_uuid: &str) -> String

Name

read_application

Purpose

Read the Wasm of a given application

Input

An instance of the FileSystem object An application’s uuid as a string

Returns

A complete .wasm file’s contents, as a string

Example

let bytecode_wasm_string = ssvm_container::storage::file_system::FileSystem::read_application(&fs, &uuid);

pub fn update_application( &self, _application_uuid: &str, _bytecode_wasm: &str, ) -> String

Name

update_application

Purpose

Update the Wasm of a given application (overrides existing .wasm file)

Input

An instance of the FileSystem object A complete .wasm file in string format

Returns

A unique identifier which can be used to access the application later

Example

ssvm_container::storage::file_system::FileSystem::update_application(&fs, &uuid, &bytecode_wasm_update);

pub fn delete_application(&self, _application_uuid: &str) -> String

Name

delete_application

Purpose

Delete the application from the file system alltogether

Input

An application’s uuid as a string
