Struct InvalidBits

pub struct InvalidBits;

Error type returned when creating a new flagset from bits is invalid or undefined.

use flagset::{FlagSet, flags};

flags! {
    pub enum Flag: u16 {
        Foo = 0b0001,
        Bar = 0b0010,
        Baz = 0b0100,
        Qux = 0b1010, // Implies Bar
    }
}

assert_eq!(FlagSet::<Flag>::new(0b01101), Err(flagset::InvalidBits)); // Invalid
assert_eq!(FlagSet::<Flag>::new(0b10101), Err(flagset::InvalidBits)); // Unknown

Trait Implementations

impl Clone for InvalidBits

fn clone(&self) -> InvalidBits

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidBits

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

Formats the value using the given formatter.

impl Display for InvalidBits

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

Formats the value using the given formatter.

impl Error for InvalidBits

Available on crate feature std only.

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 InvalidBits

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