Enum UsageError 

pub enum UsageError {
    MaxDepthExceeded(usize),
    TypeMismatch {
        key: String,
        left_type: String,
        right_type: String,
    },
}

Error types for usage operations.

Variants

MaxDepthExceeded(usize)

Maximum recursion depth exceeded.

TypeMismatch

Type mismatch between left and right values.

Fields

key: String

left_type: String

right_type: String

Trait Implementations

impl Clone for UsageError

fn clone(&self) -> UsageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsageError

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

Formats the value using the given formatter.

impl Display for UsageError

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

Formats the value using the given formatter.

impl Error for UsageError

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 UsageError

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