Implementations

impl Model

pub fn storage_root() -> PathBuf

Returns the base directory for interpreter file storage from the environment.

pub fn full_directory_path(module_id: i64, assignment_id: i64) -> PathBuf

Computes the full directory path based on module ID and assignment ID.

pub async fn save_file( db: &DatabaseConnection, assignment_id: i64, module_id: i64, filename: &str, command: &str, bytes: &[u8], ) -> Result<Self, DbErr>

pub fn load_file(&self) -> Result<Vec<u8>, Error>

Load interpreter file content from disk.

pub fn delete_file_only(&self) -> Result<(), Error>

Trait Implementations

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Model

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

Transform the error from instantiating a Model from a [QueryResult] and converting it to an Option

fn from_query_result_nullable( res: &QueryResult, pre: &str, ) -> Result<Self, TryGetError>

fn into_active_model(self) -> ActiveModel

Method to call to perform the conversion

Get the [Value] of a column from an Entity

fn set(&mut self, c: <Self::Entity as EntityTrait>::Column, v: Value)

Set the [Value] of a column in an Entity

fn find_related<R>(&self, _: R) -> Select<R>

where R: EntityTrait, Self::Entity: Related<R>,

Find related Models

fn find_linked<L>(&self, l: L) -> Select<<L as Linked>::ToEntity>

where L: Linked<FromEntity = Self::Entity>,

impl PartialEq for Model

fn eq(&self, other: &Model) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
