Enum OptionError 

pub enum OptionError {
    BadSuboption {
        option: String,
        given: String,
    },
    Removed {
        option: String,
        since: &'static str,
        instead: &'static str,
    },
    NoEffect {
        option: &'static str,
        why: &'static str,
        warning: bool,
    },
    UnsupportedCodePage(u16),
    UnknownFlag(String),
}

What an option could not do. Each but UnsupportedCodePage and UnknownFlag is a message IBM’s compiler gives and carries on from (assumptions C120 to C122).

Variants

BadSuboption

A suboption the option does not have: the option is discarded.

Fields

option: String

given: String

Removed

A suboption IBM removed, replaced by instead.

Fields

option: String

since: &'static str

instead: &'static str

NoEffect

An option Enterprise COBOL 6.4 does not have, given a warning or (warning false) an informational message and no effect.

Fields

option: &'static str

why: &'static str

warning: bool

UnsupportedCodePage(u16)

UnknownFlag(String)

Trait Implementations

impl Clone for OptionError

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 OptionError

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

Formats the value using the given formatter.

impl Display for OptionError

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

Formats the value using the given formatter.

impl Eq for OptionError

impl Error for OptionError

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 OptionError

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

Equality operator ==.

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

Inequality operator !=.
