Struct AssignReadOnlyError 

pub struct AssignReadOnlyError {
    pub name: String,
    pub new_value: Value,
    pub read_only_location: Location,
    pub vacancy: Option<Vacancy>,
}

Error returned on assigning to a read-only variable

Fields

name: String

Name of the read-only variable

new_value: Value

Value that was being assigned

read_only_location: Location

Location where the variable was made read-only

vacancy: Option<Vacancy>

State of the variable before the assignment

If this assignment error occurred in a parameter expansion as in ${foo=bar} or ${foo:=bar}, this field is Some, and the value is the state of the variable before the assignment. In other cases, this field is None.

Trait Implementations

impl Clone for AssignReadOnlyError

fn clone(&self) -> AssignReadOnlyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssignReadOnlyError

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

Formats the value using the given formatter.

impl Display for AssignReadOnlyError

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

Formats the value using the given formatter.

impl Error for AssignReadOnlyError

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<AssignReadOnlyError> for ErrorCause

fn from(source: AssignReadOnlyError) -> Self

Converts to this type from the input type.

impl PartialEq for AssignReadOnlyError

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