Struct GenError 

pub struct GenError {
    pub usage: bool,
    pub message: String,
}

Available on non-WebAssembly only.

Why a generator refused.

Fields

usage: bool

true: the request itself is wrong (a bad name or type, a missing argument) — exit code 2; false: the project isn’t in a state the generator can work with — exit code 1.

message: String

Implementations

impl GenError

pub fn to_json(&self) -> String

{"status":"refused"|"usage","error":…}.

Trait Implementations

impl Clone for GenError

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 GenError

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

Formats the value using the given formatter.

impl Display for GenError

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

Formats the value using the given formatter.

impl Eq for GenError

impl Error for GenError

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 GenError

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

Equality operator ==.

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

Inequality operator !=.
