Enum PresetError 

pub enum PresetError {
    WrongInstrument {
        saved: String,
        wanted: String,
    },
    ParamCountMismatch {
        saved: usize,
        wanted: usize,
    },
    LayoutMismatch {
        saved: String,
        wanted: String,
    },
    Corrupt {
        declared: usize,
        actual: usize,
    },
    NameEmpty,
    NameTooLong {
        len: usize,
        max: usize,
    },
    BankFull {
        max: usize,
    },
}

Why a preset was refused. Every variant carries the numbers the caller needs to say what went wrong rather than a pre-formatted sentence.

Trait Implementations

impl Clone for PresetError

fn clone(&self) -> PresetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PresetError

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

Formats the value using the given formatter.

impl Display for PresetError

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

Formats the value using the given formatter.

impl Eq for PresetError

impl Error for PresetError

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 PresetError

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

Equality operator ==.

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

Inequality operator !=.
