A single producer-side construction-invariant violation.

Variants

EmptyVersion

A tool version must contain at least one non-whitespace character.

EmptyCommandTree

The command tree has no nodes (it must contain at least the root).

CommandIndexOutOfBounds

A command-index references a node outside the command tree.

Fields

index: i32

len: usize

InvalidIdentifier

An identifier-like string does not match is_valid_identifier.

Fields

kind: &'static str

value: String

DuplicateSubcommandName

Two sibling subcommands share a name or alias.

Fields

parent: String

name: String

DuplicateName

Two names (option/flag long names, aliases, positional names) collide within a command body’s scope (including inherited globals).

Fields

command: String

name: String

DuplicateShort

Two short forms collide within a command body’s scope.

Fields

command: String

short: char

UnresolvedConstraintRef

A constraint ref names something not in scope.

Fields

command: String

name: String

ValueIsTypeMismatch

A value-is literal is not a valid value for the referenced name’s declared type.

Fields

command: String

name: String

DefaultTypeMismatch

A default literal is not a valid value for its option/positional’s declared type (a repeatable option’s default must be a list of its element type).

Fields

command: String

name: String

RepeatableMapTypeNotMap

A repeatable-map option’s collected map_type does not resolve to a SchemaType::Map (the collected key-value value must be a map node).

Fields

command: String

name: String

UnresolvedTypeRef

An embedded type contains a SchemaType::Ref whose id does not resolve to a definition in the tool’s SchemaGraph.

Fields

command: String

position: String

id: String

IllFormedSchema

An embedded type is not structurally well-formed (for example an inverted numeric min > max, an empty variant, or a non-primitive map key), as reported by schema well-formedness validation.

Fields

command: String

position: String

detail: String

DuplicateTypeId

Two definitions in the tool’s SchemaGraph share the same type id; the wire encoder requires definition ids to be unique.

Fields

id: String

UnresolvedDefaultFormatter

A body’s default-formatter does not resolve to one of its formatters.

Fields

command: String

formatter: String

VerbatimWithoutSeparator

A tail-positional declares verbatim = true without a separator.

Fields

command: String

positional: String

VariantInInputPosition

A variant type is reachable from an input position; input-side discrimination must use union instead.

Fields

command: String

position: String

UnreachableCommandNode

A command-tree node is not reachable from the root.

Fields

index: i32

CommandTreeCycle

The command tree contains a cycle.

Fields

index: i32

DuplicateCommandParent

A command-tree node is referenced as a subcommand by more than one parent (the command graph is a DAG, not a tree).

Fields

index: i32

Trait Implementations

impl Clone for ToolValidationError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolValidationError

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

Formats the value using the given formatter.

impl Display for ToolValidationError

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

Formats the value using the given formatter.

impl Eq for ToolValidationError

impl Error for ToolValidationError

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 PartialEq for ToolValidationError

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

Equality operator ==.

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

Inequality operator !=.
