Enum branchless::git::MaybeZeroOid

source · [−]

pub enum MaybeZeroOid {
    Zero,
    NonZero(NonZeroOid),
}

Expand description

Represents an OID which may be zero or non-zero. This exists because Git often represents the absence of an object using the zero OID. We want to statically check for those cases by using a more descriptive type.

This type is isomorphic to Option<NonZeroOid>. It should be used primarily when converting to and from string representations of OID values.

Variants

`Zero`

The zero OID (i.e. 40 0s).

`NonZero(NonZeroOid)`

A non-zero OID.
