Enum Compare 

pub enum Compare<'a> {
    Equal(&'a [u8]),
    NotEqual(&'a [u8]),
    DigestEqual(u64),
    DigestNotEqual(u64),
}

What a conditional write compares the current value against.

Variants

Equal(&'a [u8])

IFEQ: the value is exactly these bytes.

NotEqual(&'a [u8])

IFNE: the value is not exactly these bytes, or there is no value.

DigestEqual(u64)

IFDEQ: the value’s digest is this number.

DigestNotEqual(u64)

IFDNE: the value’s digest is not this number, or there is no value.

Implementations

impl Compare<'_>

pub fn holds(&self, current: Option<Str<'_>>) -> bool

Whether the condition holds against what is stored, where None is a key that is not there.
