}

Possible states of the task

Variants

New

The task is ready to be executed

InProgress

The task is being executed.

impl Clone for FangTaskState

fn clone(&self) -> FangTaskState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FangTaskState

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

Formats the value using the given formatter.

impl Default for FangTaskState

fn default() -> FangTaskState

Returns the “default value” for a type.

impl<'a> FromSql<'a> for FangTaskState

fn from_sql( _type: &Type, buf: &'a [u8] ) -> Result<FangTaskState, Box<dyn Error + Sync + Send>>

Creates a new value of this type from a buffer of data of the specified Postgres Type in its binary format.

fn accepts(type_: &Type) -> bool

Determines if a value of this type can be created from the specified Postgres Type.

fn from_sql_null( ty: &Type ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>

Creates a new value of this type from a NULL SQL value.

fn from_sql_nullable( ty: &Type, raw: Option<&'a [u8]> ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>

A convenience function that delegates to from_sql and from_sql_null depending on the value of raw.

impl FromSql<FangTaskStateEnum, Pg> for FangTaskState

fn from_sql(raw: PgValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql( bytes: Option<<DB as Backend>::RawValue<'_>> ) -> Result<Self, Box<dyn Error + Sync + Send, Global>>

A specialized variant of from_sql for handling null values.

impl PartialEq<FangTaskState> for FangTaskState

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Queryable<FangTaskStateEnum, Pg> for FangTaskState

type Row = FangTaskState

The Rust type you’d like to map from.

fn build(row: Self::Row) -> Result<Self>

Construct an instance of this type

impl ToSql<FangTaskStateEnum, Pg> for FangTaskState

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, Pg>) -> Result

See the trait documentation.

impl<DB> ToSql<Nullable<FangTaskStateEnum>, DB> for FangTaskStatewhere DB: Backend, Self: ToSql<FangTaskStateEnum, DB>,

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, DB>) -> Result

See the trait documentation.

impl ToSql for FangTaskState

fn to_sql( &self, _type: &Type, buf: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

Converts the value of self into the binary format of the specified Postgres Type, appending it to out.

fn accepts(type_: &Type) -> bool

Determines if a value of this type can be converted to the specified Postgres Type.

fn to_sql_checked( &self, ty: &Type, out: &mut BytesMut ) -> Result<IsNull, Box<dyn Error + Sync + Send>>

An adaptor method used internally by Rust-Postgres.
