Enum KanbanCliError 

pub enum KanbanCliError {
    Domain(KanbanError),
    Resolution {
        hint: String,
    },
    Io(Error),
    Serialization(Error),
}

CLI-boundary error type.

Wraps KanbanError for the domain layer, plus CLI-specific concerns (handler-built messages, IO, serialization). Handlers that return Result<T, KanbanCliError> propagate all failure modes uniformly with ?, and the dispatcher converts to the JSON CliResponse envelope at the boundary.

Variants

Domain(KanbanError)

Resolution

Handler-built user-facing message at the CLI boundary.

Named to match the MCP-side KanbanMcpError::Resolution so the two surfaces stay symmetric. Used when a handler has enough input context to enrich an otherwise anonymous domain error (cycle detected: making A a parent of B would create a cycle). Identifier-resolution failures flow through Domain directly so the structured kanban_domain::DomainError::NotFoundByName / Ambiguous variants stay introspectable.

Display renders the hint verbatim, no wrapper prefix, matching the established CLI convention used by card get / card delete / card archive.

Fields

hint: String

Io(Error)

Serialization(Error)

Trait Implementations

impl Debug for KanbanCliError

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

Formats the value using the given formatter.

impl Display for KanbanCliError

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

Formats the value using the given formatter.

impl Error for KanbanCliError

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
