Enum A2aError 

#[non_exhaustive]
pub enum A2aError {
    Read {
        path: PathBuf,
        source: Error,
    },
    Parse {
        path: PathBuf,
        problem: &'static str,
        line: usize,
        column: usize,
    },
    NoAgents {
        path: PathBuf,
    },
    Invalid {
        origin: String,
        name: String,
        reason: String,
    },
}

Anything that can go wrong turning configuration into agents.

McpError’s rule, for its reason: these messages travel into basis spawn --json, an ACP client’s error pane and whatever a host logs, and a headers value is a credential — already expanded by the time it could be repeated. A message may name the file, the agent, the field, a header’s name and an environment variable, and nothing else it read. Parse keeps a location and a category instead of serde’s own message, which quotes the value it choked on; an unknown key is therefore reported as a place in the file rather than as the word that was wrong.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Trait Implementations

impl Debug for A2aError

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

Formats the value using the given formatter.

impl Display for A2aError

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

Formats the value using the given formatter.

impl Error for A2aError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<A2aError> for RunError

fn from(source: A2aError) -> Self

Converts to this type from the input type.
