Enum ChannelState 

pub enum ChannelState {
    Submitted,
    Working,
    InputRequired,
    Completed,
    Failed,
    Canceled,
    Rejected,
    Stale,
}

A2A v0.3 lifecycle vocabulary, serialized on the wire as kebab-case (input-required, canceled, etc.).

Spelling note

Canceled (→ "canceled") intentionally follows the A2A v0.3 spec spelling and is a DISTINCT type from crate::a2a::TaskState, which spells the equivalent variant Cancelled (two l’s). The two enums are bridged by an explicit boundary mapping — not string equality — so the spelling difference is deliberate, not a bug.

Variants

Submitted

Working

InputRequired

Completed

Failed

Canceled

Rejected

Stale

MUR extension (not in A2A v0.3): the channel has had no activity for an extended period and was system-marked stale.

Trait Implementations

impl Clone for ChannelState

fn clone(&self) -> ChannelState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChannelState

impl Debug for ChannelState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChannelState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ChannelState

impl PartialEq for ChannelState

fn eq(&self, other: &ChannelState) -> 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.

impl Serialize for ChannelState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
