Enum VerRes

pub enum VerRes {
    Ok(usize),
    ZeroLen,
    Unknown,
}

Versatile result enumeration.

Used by various methods in versatile way.

Variants

Ok(usize)

Operation accomplished.

ZeroLen

Zero occurrent usage.

Unknown

Unknown occurrent usage.

Implementations

impl VerRes

pub const fn is_ok(&self) -> bool

Returns true for VerRes::Ok(_).

pub const fn unwrap(&self) -> usize

Returns usize of VerRes::Ok(usize) or panics if not that variant.

pub const unsafe fn unwrap_unchecked(&self) -> usize

Returns usize of VerRes::Ok(usize) and does not panic if not that variant (UB).

Check with std::hint::unreachable_unchecked for more information.

Trait Implementations

impl Debug for VerRes

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

Formats the value using the given formatter.

impl PartialEq for VerRes

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