Enum CoroState 

#[repr(u8)]
pub enum CoroState {
    Created = 0,
    Running = 1,
    Yielded = 2,
    Awaiting = 3,
    Returned = 4,
    Failed = 5,
}

The state of a coroutine, as Inst::CoroStatus reports it (a u8 code).

Created --resume--> Running --yield--> Yielded  --resume--> Running ...
                       |    --await--> Awaiting --resume--> Running ...
                       |    --ret----> Returned
                       +--- error escapes the body --> Failed

Examples

use bytecode_lang::CoroState;

assert_eq!(CoroState::Awaiting.code(), 3);
assert_eq!(CoroState::from_code(4), Some(CoroState::Returned));
assert!(CoroState::Yielded.is_resumable());
assert!(!CoroState::Failed.is_resumable());

Variants

Created = 0

Made by coro_new, never resumed: its body has not started.

Running = 1

Executing: it is the running coroutine or one of its resumers.

Yielded = 2

Suspended by yield.

Awaiting = 3

Suspended by await.

Returned = 4

Its body returned; it can never run again.

Failed = 5

An error escaped its body; it can never run again.

Implementations

impl CoroState

pub const ALL: &'static [CoroState]

Every value, in code order.

pub const fn from_code(code: u8) -> Option<Self>

The value with this stable code, or None if no value has it.

pub const fn code(self) -> u8

The stable code this value is encoded as.

pub const fn name(self) -> &'static str

The lowercase name the disassembler prints.

impl CoroState

pub const fn is_resumable(self) -> bool

Whether resume, resume_throw, and coro_close would run code in a coroutine in this state (Created, Yielded, or Awaiting).

Examples

use bytecode_lang::CoroState;

assert!(CoroState::Created.is_resumable());
assert!(!CoroState::Running.is_resumable());

Trait Implementations

impl Eq for CoroState

impl Hash for CoroState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl Ord for CoroState

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.
